5 Lessons from Engr Uzodimma Odimuko’s Presentation

Technology has become so familiar that we barely think about what makes it work.

We make video calls, stream movies, use AI, send files across continents and access information within seconds.

Behind these simple actions is a vast system of radio frequencies, microchips, fibre optic cables, data centres and communication networks.

On Saturday, April 25, 2026, Engr Uzodimma Odimuko, Class of 2000, revealed this technological system to DIAA members through his presentation “Beyond the Handset: Scaling Networks to Connect Machines and Intelligence“.

Here are five lessons from the presentation.

1. Successful Companies Continue to Adapt

 

Nokia is remembered by many people as one of the companies that dominated the mobile phone industry.

Uzo explained that Nokia had operated in industries such as paper and rubber before becoming one of the world’s major telecommunications companies.

The ability to change is important.

A company can become very successful at one technology and still struggle when the market changes. Nokia experienced this when smartphones transformed the mobile phone industry.

The company lost its dominant position in handsets, but Nokia did not disappear. It shifted its attention to telecommunications infrastructure, networking equipment and cloud technology.

Past success gives us experience and resources. It does not guarantee future relevance.

Markets change. Customer behaviour changes. Technology changes.

We have to keep watching what is happening around us and develop the ability to respond before change makes our existing skills or business models less valuable.

2. The Technology We Use Every Day Depends on Enormous Infrastructure

 

A smartphone appears simple when we hold it in our hands.

But the system behind it is not simple.

Uzo explained how telecommunications begins with the electromagnetic spectrum. Governments regulate this spectrum and allocate frequencies to telecommunications companies and other users.

Those frequencies allow information to travel wirelessly.

Then there are microchips.

Modern chips contain billions of tiny electronic switches known as transistors. These transistors form the logic gates that allow computers and other electronic devices to process information.

The cloud is sometimes described as though information floats around the internet. Uzo explained that the cloud consists of physical infrastructure: huge data centres containing servers, storage equipment and networking systems.

These data centres are connected across countries and continents through high capacity networks, including submarine fibre optic cables running along the seabed.

When you send a WhatsApp message from Lagos to someone in London or New York, several layers of infrastructure are involved.

What appears effortless to you depends on decades of scientific research, massive investments and technological equipment spread across continents.

3. Microchips Have Become Part of Global Politics

 

Advanced computer chips contain billions of microscopic transistors.

Uzo discussed ASML, the Dutch company that produces the extreme ultraviolet lithography systems used in manufacturing the world’s most advanced semiconductors.

That technology has become important because advanced chips power AI systems, telecommunications infrastructure, military technology, data centres and many other critical industries.

Countries have started treating access to semiconductor technology as an issue of national security.

The United States and some of its allies have restricted China’s access to certain advanced chipmaking technologies as competition between the two countries expands into artificial intelligence.

This tells us something about the modern economy.

Resources that determine national power are changing.

Oil, minerals, factories and military equipment are still important. Computing power, semiconductors, AI, telecommunications infrastructure and data are increasingly important too.

Technology is now shaping international politics as much as international politics is shaping technology.

4. The Next Communication Revolution Will Connect Machines

 

3G made mobile internet possible.

4G helped services such as YouTube, Instagram, Spotify and other data intensive applications become part of everyday life.

5G is taking communications in another direction.

Mining companies can operate enormous autonomous trucks. Ports can automate parts of their operations. Warehouses can use autonomous mobile robots to move goods.

These machines need to communicate quickly with other machines and computer systems.

The future of telecommunications extends far beyond people making calls or browsing the internet.

Factories, vehicles, robots, sensors, ports, mines and other infrastructure will increasingly communicate through networks.

The handset may eventually become only one small part of a much larger connected world.

5. Young People Need Depth, Curiosity and Strong Foundations

 

Uzo mentioned subjects like data science, networking, cybersecurity and DevOps as areas young Dorityans should study if they want careers in the global technology industry.

He advised young people to choose an area of study and build deep knowledge in that area instead of trying to pursue everything at the same time.

New courses, certifications, programming languages and career opportunities appear every week.

Trying to learn everything can produce shallow knowledge of many subjects.

Curiosity helps us explore. Focus allows us to develop expertise.

Much of the science behind Uzo’s presentation could be traced back to concepts taught in secondary school physics.

Students may sometimes wonder why they have to learn subjects that appear disconnected from their future careers.

Years later, those same concepts may become the foundation for understanding telecommunications, engineering, computing or another profession.

Member’s Corner: Prof Chinelo Ezeocha

Member’s Corner takes a closer look at Dority International Alumni Association members. This month, August 2026, features Professor Chinelo Ezeocha from Class of 1997.

 

 

Chinelo Vanessa Ezeocha is a dedicated academic, researcher, and mentor in in Food Science and Technology, with extensive experience in teaching, research, innovation, and community service. 

She is a 1997 graduate of DISS and holds B.Sc., M.Sc., and PhD degrees in Food Science and Technology. A recipient of the African Women in Agricultural Research and Development (AWARD) Fellowship, she completed Advanced Science Training at the Agricultural Research Centre for International Development (CIRAD) in Montpellier, France, and served as a Visiting Researcher at CORAF/WECARD in Dakar, Senegal.

She began her career at the National Root Crops Research Institute, Umudike, where she rose to the rank of Senior Research Officer. In 2015, she joined Michael Okpara University of Agriculture (MOUAU), where she progressed through the academic ranks to become a Professor of Food Science and Technology. She is currently on sabbatical leave at the Federal University of Technology, Owerri (FUTO).

Professor Ezeocha is a Fellow of the Nigerian Institute of Food Science and Technology, a Certified Food Scientist (CFS), and a member of several other related professional bodies.

 

When did you first become interested in Food Science and Technology, and why did you choose it as a career?

As a child I had always been very selective when it comes to food, I always complained about the monotonous diet at home and when I did, my mum would ask me to go to the kitchen and fix the so called special diet myself. So I always found myself in the kitchen experimenting with recipes, some of which turned out great, while some others were nasty.

When it was time to choose what to study, I knew I wanted to do something related to food which was completely against what my parents wanted for me. I discussed my passion with my uncle who then advised me to go for Food Science and Technology since I performed well in my sciences and mathematics.

He helped me convince my parents and that was how my journey in Food Science and Technology started. Since then, I decided to work hard to prove to my parents that my career choice was the right one for me and I am happy that they later agreed with me.

What important lessons did you learn during your time at the National Root Crops Research Institute, Umudike?

My journey in the research world started at National Root Crops Research Institute (NRCRI), Umudike, where I learnt how to identify practical challenges facing farmers, processors and consumers and develop innovative solutions. I also learnt patience, perseverance, how to pay attention to details while working with data and how to collaborate and work within a multidisciplinary team.

I was also exposed to a lot of trainings and short courses such as the ones organized by IITA, CIRAD, Wageningen University etc. The years I spent in NRCRI were my formative years which laid the solid foundation on which I stand today.

What were the most significant challenges on your journey to becoming a professor?

The greatest challenge on my journey to becoming a Professor was time management. It was not easy balancing the demands of teaching, research and family responsibilities.

Another challenge was working in an environment where research infrastructure and funding were usually inadequate. This pushed me to become resourceful, collaborate with colleagues from better equipped institutions and seek for funding opportunities, which were very competitive, to strengthen my research and professional development.

Despite these challenges I faced, perseverance, mentorship and the passion for advancing knowledge kept me motivated.

How does your research in food processing, preservation and value addition improve the lives of ordinary households, farmers and entrepreneurs?

My research is aimed at improving food security, nutrition and livelihoods. By developing simple, affordable and sustainable processing technologies and value-added products, my research contributes to the reduction of post-harvest losses, extension of shelf life and improvement in the quality and safety of food products made from locally available crops.

These can increase the economic value of these crops and minimize waste for farmers. I always ensure that my research work always translate into real benefits for communities through improved nutrition, increased income and sustainable food systems.

How did the AWARD Fellowship and your research experiences in France and Senegal influence your professional development?

The African Women in Agricultural Research and Development (AWARD) fellowship was a transformative milestone in my professional development. It equipped me with leadership, mentorship and proposal writing skills, enabling me to build stronger research collaborations and compete more effectively for research funding.

Through the advanced science training, I was exposed to state-of-the-art research facilities and cutting-edge analytical techniques. These experiences have shaped my approach to research and teaching.

They inspired me to pursue excellence, foster collaborations, mentor young scientists and conduct research that benefit my community.

What challenges have you encountered as a woman working in agricultural research and academia, and how did you overcome them?

One of the greatest challenges I encountered as a working woman was balancing the demands of teaching, research, mentorship, and administrative duties with family and personal responsibilities simultaneously, often under serious time constraints.

Most times, I had to work extra hard to establish credibility and demonstrate my capabilities above my male colleagues.

Mentorship by senior colleagues, participation in initiatives such as AWARD and my international experiences gave me the confidence to pursue ambitious goals. By remaining resilient, maintaining high professional standards and focusing on research that addressed real societal needs, I was able to build a rewarding career.

Today, I am passionate about mentoring young women scientists, encouraging them to believe in their abilities, that with determination, integrity and hard work, they can overcome barriers.

You have supervised many undergraduate and postgraduate students. What principles guide your approach to teaching and mentorship?

I have always believed that education is not only about imparting knowledge but also inspiring curiosity, critical thinking and innovation.

So I try to create a supportive and inclusive learning environment where students are encouraged to ask questions, explore ideas and develop confidence in their abilities.

I encourage my students to think independently and equip them with what it takes to become problem solvers, effective communicators, team players and future leaders. One of the most rewarding aspects is seeing my former students excel in the real world after graduation.

I met one of my students in Italy during one of my industrial visits and I was very happy when his supervisor was speaking highly of him. Such achievements reaffirm my belief in mentorship.

What have you learnt from training master bakers, women’s groups, young people and entrepreneurs to develop products from indigenous crops?

Training these various groups of people has taught me that scientific knowledge has its greatest value when it is translated into practical solutions that improve people’s lives and livelihoods.

This helped me to realize that innovation must be pertinent to local needs and that capacity building is as important as technology development.

I also learnt that the most successful innovations are those developed by combining scientific expertise with local experience because they usually give rise to practical, affordable and culturally acceptable solutions.

You mentioned Mrs. Zovannah Onumah’s influence on you as a student. Was there another person, teacher or experience at Dority that significantly influenced your future?

The collective influence of the teachers and values promoted at Dority laid the foundation for my future. However, the teachers that had the most significant influence were Monsieur Abosi Mukete and Mr. Moses Ineh.

Monsieur Abosi Mukete taught us how fun learning a new language could be, he taught us nice songs and we also acted drama in French. Those experiences gave me the confidence and open mind I needed during my sojourn in non-English speaking countries.

Mr. Moses Ineh taught us discipline which is one of the principles that has guided my academic and professional journey.

The JETS club competition we went for in Ogun State was what triggered my interest in science, and I remain grateful for such experiences.

What advice would you give to Dority students and younger alumni who want to build meaningful careers in the agriculture and food industry?

My advice to Dority students and younger alumni is to pursue their dreams with purpose, curiosity and perseverance.

They should first build a strong academic foundation and never stop learning since technology is constantly evolving, they should remain open to new ideas and innovations.

They should also work hard, remain resilient, seek mentors and build meaningful professional networks, collaborate and take advantage of internships, research opportunities and professional development programmes that will broaden their experience.

Most importantly, they should use their knowledge to improve their community.

5 Lessons from Uzoma Ekwebelem’s Presentation

Building a business from nothing involves uncertainty, risk, rejection and many difficult days.

On Saturday, June 27, 2026, Uzoma Ekwebelem (Class of 2002) delivered a presentation titled “The Courage to Build: Lessons from the Boardroom to Entrepreneurship” as part of DIAA’s monthly Knowledge Sharing Series.

She spoke about her decision to become an entrepreneur and explained how she built Arya Marketplace, a business-to-business platform connecting African manufacturers, wholesalers and distributors with buyers across the continent.

Here are five lessons from her presentation.

1. Dority Influenced Us

Uzoma Ekwebelem Presentation image

According to Uzoma, Dority taught her discipline.

She was expected to arrive early to school, complete her assignments, attend evening lessons and sometimes return for Saturday classes.

These demands felt difficult at the time. But Uzoma later realised that they helped her develop discipline and resilience.

The lesson is that education goes beyond the subjects taught in the classroom.

Schools influence our habits and attitudes, and the discipline we complain about as students may become our greatest advantage as adults.

2. Companies Grow Through Systems

Uzoma Ekwebelem Presentation image 2

Uzoma spent about fifteen years working at IBM and Oracle.

Before entering the corporate world, she believed that business success came mainly from having brilliant people.

She soon realised that brilliant people weren’t enough. Successful companies build systems that continue to function when employees and leaders change.

Many Nigerian businesses revolve around one person. The founder makes every decision, supervises every task and holds most of the important information.

When that person is unavailable, work slows down or stops completely.

A business operating this way cannot grow beyond the capacity of its founder.

In large corporate organisations, employees receive responsibilities and are assessed according to agreed Key Performance Indicators. They aren’t followed around and told what to do every hour.

A business becomes scalable and successful when its important activities can continue without the founder personally managing every step.

3. Growth Requires Discomfort

Uzoma Ekwebelem Presentation image 3

After working at IBM and Oracle for many years, Uzoma faced an important decision.

She could remain in a successful corporate career with a good salary and a predictable path. Or she could leave that security and build something of her own.

Uzoma decided that she would rather try and fail than reach a point in her life where she regretted not trying.

Entrepreneurship gave her freedom, but it also brought uncertainty and financial risk.

There was no guarantee that her business would succeed.

Meaningful growth requires us to do something unfamiliar. Growth doesn’t happen within our comfort zone.

We may need to accept a new responsibility, enter a different industry, acquire a difficult skill or attempt a project with an uncertain outcome.

4. Successful Businesses Solve Real Problems

Uzoma Ekwebelem Presentation image 4

Uzoma’s interest in engineering, manufacturing and business led her to the problem Arya Marketplace was created to solve.

Aba produces shoes, clothes, bags and many other products. However, local manufacturers struggle to reach buyers outside their immediate environment.

Arya Marketplace solved this problem by connecting Aba manufacturers with buyers across Nigeria.

The company has onboarded more than 1,000 merchants, developed a buyer community of over 1,000 people and listed approximately 7,500 products.

The long-term plan is to extend the business model to other commercial centres in Nigeria and across Africa.

We don’t have to search far away for business opportunities.

Some of the most valuable opportunities are hidden inside the problems affecting our communities.

5. Resilience, Relationships and Reputation Matter

Uzoma Presentation image 5

Uzoma made us understand that while talent may create opportunities for you, resilience helps you make the most of those opportunities.

Resilience enables you to continue working when things go wrong. It helps you recover from rejection and solve unexpected problems.

Relationships also matter. Uzoma’s move to Oracle resulted from a recommendation by a former IBM colleague.

Every person who comes into our lives impacts us in one way or another. They may teach us, recommend us for opportunities, support our work or connect us with others.

Reputation is also important. A good reputation takes years to build but can be destroyed quickly.

People remember how we treat them, whether we keep our promises and whether we act with honesty when nobody is watching.

Resilience, relationships and reputation produce results gradually, with their value increasing over time.
