2024 Class of MGB-SIAM Early Career Fellows

SIAM is excited to announce the 2024 Class of MGB-SIAM Early Career Fellows. These accomplished early career professionals were chosen based on their achievements; active support of diversity, equity, and inclusion in their communities; and dedication to industrial and applied mathematics, computational science, and data science.

The MGB-SIAM Early Career Fellowship is a collaborative initiative by Mathematically Gifted & Black (MGB) and SIAM, aiming to foster prolonged engagement of fellows within SIAM and ensure their continued success in the broader applied mathematics and computational sciences community. This program recognizes the achievements of early career applied mathematicians — with a particular focus on those from racial and ethnic groups historically excluded from the mathematical sciences in the United States — and provides professional activities and career development. The 2024 fellows were chosen by a selection committee consisting of the SIAM Vice President for Equity, Diversity, and Inclusion; MGB representatives; and SIAM members.

SIAM extends heartfelt congratulations to these eight members of the community for their well-deserved recognition as the 2024 Class of MGB-SIAM Early Career Fellows. Read more about our newest fellows.

Sarafa Adewale Iyaniwura, Los Alamos National Laboratory


Dr. Sarafa Adewale Iyaniwura is a postdoctoral research associate in the Theoretical Biology and Biophysics group at Los Alamos National Laboratory (LANL). Born and raised in Nigeria, Dr. Iyaniwura obtained his B.Sc. in mathematics from the University of Ilorin, his M.Sc. in mathematical sciences from the African Institute for Mathematical Sciences, and his Ph.D. in applied mathematics from the University of British Columbia (UBC). While at UBC, he was a member of the Institute of Applied Mathematics.

Dr. Iyaniwura’s research interests lie in using mathematical models to gain insight into complex biological systems. He is interested in developing mathematical frameworks for calculating the mean first passage time for active and passive Brownian particles to escape a region and applying this phenomenon to biological systems. He’s also interested in using reaction-diffusion systems to study collective behavior among biological cells, quorum sensing, and diffusion-mediated communication. 

Furthermore, Dr. Iyaniwura uses mechanistic mathematical models to study infectious diseases at the individual and population levels. He uses stochastic and deterministic models and data science techniques. The deterministic models are analyzed using asymptotic analysis, bifurcation analysis, strong localized perturbation theory, and local stability analysis. He also uses numerical techniques such as the finite difference method, finite element method, and the closest point method. Dr. Iyaniwura informs his models with biological datasets and calibrates them to these datasets using maximum likelihood estimates and Bayesian inference framework. He also collaborates with biologists, experimentalists, clinicians, and public health officials to provide insight into their datasets and provide them with modeling support.
