Role

Senior Lecturer in Statistics, Department of Mathematics, School of Science and Technology

As a Senior Lecturer at Nottingham Trent University, consultant, and council member of the Royal Statistical Society, Dr Ulgen leads research and teaching initiatives focused on advancing public health, statistical epidemiology, and statistical genetics.

Dr. Ulgen’s expertise encompasses data science, biostatistics, and statistical genetics, including machine learning, mediation analysis, survival analysis methodologies, multivariate and random effects modelling, and genome-wide linkage and association studies which play a crucial role in the understanding of complex diseases such as COVID-19, cancer, aging, respiratory and neuro-psychiatric disorders. Dr. Ulgen leads and manages interdisciplinary collaborations between researchers, industry, and policy-makers.

As a newly elected member of the council of the Royal Statistical Society, Dr. Ulgen is focused on promoting how data science and AI can improve health outcomes, and the potential consequences of polarization. She is interested in how to overcome these biases and the importance of investing in data science and AI scientifically and economically.

Career overview

With over 15 years of experience in research, consulting, teaching, and scientific diplomacy in academia, biotechnology, and non-governmental sectors, Dr. Ulgen has led and worked on projects extensively in the areas of medical diagnostics, pharmacogenomics, public health, and epidemiology, involving the elucidation of risk factors and complex genetic mechanisms underlying multifactorial diseases at the international and national levels.

As a Fulbright and Chevening Scholar, she has successfully led and contributed to high-impact projects, including UKRI, MRC, NIH-RO1, NSF, and NIMH-funded initiatives, BARDA, Mass Life Science and Small Business Innovation Research (SBIR) grants as well as the French National Study on the Epidemiology and Genetics of Asthma and EU project network of excellence in GABRIEL and GaLEN.

Dr. Ulgen demonstrates visionary leadership through strategic approaches to bridging academic research and industry innovation. By cultivating cross-sector collaborations, she effectively transforms scientific knowledge into practical applications. One of her most recent accomplishments is the management of the machine learning and pre-clinical validation of Botanisol’s COVID-19 diagnostic screener in collaboration with the Harvard School of Medicine. Dr. Ulgen has recently secured an International Partnership Fund, where she is forming research collaborations between UGenome AI, University of Arizona, and the Centre for Computer Science and Informatics, MTIF, and Biological Sciences at NTU. As a PI and Co-PI on various projects, she has mentored students, secured international collaborations, and contributed to global efforts in public health and the environment.

Dr. Ulgen holds memberships in prestigious academic societies, including the London Mathematical Society, Society for Epidemiologic Research, and Royal Statistical Society (as a Fellow). She is also a Fellow of the UK Higher Education Academy (FHEA). Currently, Dr. Ulgen spearheads Equality, Diversity, and Inclusivity initiatives within her department, demonstrating her commitment to fostering an inclusive academic environment alongside her research and teaching pursuits. One of her favourite sayings is ‘"Why treat people and send them back to the conditions that made them sick?" - Sir Michael Marmot. Dr. Ulgen is committed to using her expertise in data science and public health to eliminate health inequalities caused by AI biases and public opinion, and to improve health outcomes for the underprivileged.

Research areas

Dr. Ayse Ulgen leads research in the fields of statistical epidemiology, data science, biostatistics, and statistical genetics. Additionally, she has research collaborations with biotech companies such as med-tech and pharmacogenomics. Dr. Ulgen is currently working on survival analyses and cause-specific competing risk analyses, machine learning applications on COVID-19, and she has extensive work in the field of statistical genetics which is an interdisciplinary field with the goal of finding human disease genes, using tools from mathematics, statistics, computer science, genetics and epidemiology (including GWAs, family-based association analyses, random effects modelling and multivariate analysis) on complex disorders such as epilepsy and neuro-psychiatric disorders, cancer, and asthma.

Dr. Ulgen’s research focuses on methodological and computational applications of data science, statistics, and epidemiology in modelling disease and public health outcomes., often bridging the gap between research and applications, aiming to create meaningful change.
