From Nigeria to Nanoparticles: The Life of Professor Dame Ijeoma Uchegbu

Early Life and Family History (1960-1974)

Professor Dame Ijeoma Uchegbu’s story begins with her parents’ ambitious move from Nigeria to the UK in 1960, seeking further education. Her name, Ijeoma, meaning “have a safe trip,” encapsulates their hopes for a successful venture. However, the realities of life in a new country led to her being placed in foster care shortly after birth, allowing her parents to focus on their studies – her mother at LSE and her father in electrical engineering. This practice, while common for West African students at the time due to established extended family support systems, initiated a period of separation and complex family dynamics. At age four, she was reunited with her father, but discovered at age ten that her stepmother was not her biological mother, a revelation that caused significant emotional distress. A brief meeting with her biological mother at age thirteen, while positive, was ultimately a one-time event. Tragically, her biological mother died in the US when Ijeoma was fourteen, leaving her with a profound sense of loss and a permanent absence. Despite these familial upheavals, her father maintained a strong Nigerian cultural presence in her upbringing, emphasizing Nigerian food, community, and a persistent hope for eventual return to Nigeria.

Navigating Racism and Education in the UK (1960s-1970s)

Growing up in the UK during the 1960s and 70s presented challenges related to racial prejudice. Ijeoma attended grammar school, a relatively uncommon opportunity for Black children at the time, with only five Black students in a class of ninety. She benefited from a supportive primary school teacher who instilled confidence in her abilities, countering the prevalent practice of placing Black children in special education based on perceived educational needs. Despite this support, she initially lacked professional aspirations, influenced by the limited representation of Black individuals in professional roles. A brief period living in Nigeria at age thirteen, however, dramatically shifted her perspective. While initially difficult due to cultural adjustment and a severe allergic reaction to the strong sunlight (an allergy she still experiences), Nigeria exposed her to Black role models and fostered a renewed sense of ambition. She excelled in science and mathematics, recognizing their universal applicability and her existing proficiency.

Return to the UK and Initial Struggles (1990)

Driven by a desire to pursue a PhD in science, Ijeoma returned to the UK in 1990 with her three young daughters and limited financial resources. This return was met with skepticism and financial hardship. She arrived with only one suitcase and minimal funds, quickly finding herself in a homeless persons unit for seven months. Conditions were dire, with multiple families sharing limited bathroom facilities and experiencing disrespectful treatment. Despite these challenges, she remained determined to provide for her daughters and pursue her academic goals. She actively sought research positions, ultimately choosing a less financially lucrative PhD opportunity focused on nanotechnology – a field she found intellectually stimulating and novel. She demonstrated resourcefulness by navigating the housing benefit system, utilizing legal resources to correct an error and secure financial assistance.

Academic Pursuit and Personal Partnership (1990s-Present)

Ijeoma’s PhD research led her to a pivotal conference where she met Andreas Schatzlein, a German scientist who would become her husband and business partner. Their connection was immediate and profound, culminating in a marriage that required Andreas to relocate to the UK and embrace a life with Ijeoma and her three daughters. Together, they founded a company focused on developing innovative medicines, particularly utilizing nanotechnology for targeted drug delivery. Their current research focuses on pain therapeutics and eye drops designed to minimize side effects by delivering medication directly to the affected area. This work holds potential for addressing the opioid crisis by developing non-addictive pain relief solutions. Ijeoma’s academic career flourished, culminating in her appointment as a professor at University College London and, subsequently, a Damehood.

Championing Equality and Inclusion

Beyond her scientific achievements, Professor Uchegbu has become a vocal advocate for equality and inclusion within academia. She discovered and actively campaigned to remove the names of prominent eugenicists from buildings at UCL, recognizing the harmful impact of their legacy on students, particularly those from marginalized backgrounds. She also championed the importance of correctly pronouncing students’ names, highlighting how this simple act of respect can foster a sense of belonging and improve academic performance. Her efforts have been met with overwhelmingly positive feedback, particularly from students who felt empowered and validated by these changes.

Reflections and Legacy

Professor Uchegbu’s life is a testament to resilience, determination, and the power of following one’s passion. She emphasizes the importance of pursuing interests over financial gain and acknowledges that her journey to the UK, while challenging, ultimately proved transformative. Her advice to her granddaughter, and to anyone seeking fulfillment, is to “follow your passion and do what really interests you.” She expresses minimal regret, except for prolonging an unhappy marriage, and finds immense pride in her accomplishments and the positive impact she has made on others. Her story underscores the importance of challenging systemic barriers and creating a more inclusive and equitable environment for all.

Notable Quotes:

• “Poverty will drive you back.” – A quote from someone in Nigeria, highlighting the societal skepticism surrounding her ambitions.
• “If you follow your passion and do what really interests you, you’ll be okay.” – Professor Uchegbu’s core advice.
• “Ijeoma” means “have a safe trip” – Reflecting her parents’ hopes for their journey to the UK.
• “We’re all in this together we have to make it work together, somehow.” – Ijeoma’s mindset regarding her daughters during their period of homelessness.

Data & Statistics:

• Five Black students in a class of ninety during Ijeoma’s grammar school years.
• 80,000 deaths annually in the US due to the opioid crisis.
• 40 weekly deaths in the UK from opioid poisoning.
• Evidence of lower degree attainment rates for ethnic minority students and reduced promotion rates for ethnic minority staff at UCL.
