Dr. Schnell's laboratory[2] investigates biochemical and biological systems comprising many interacting components, where modeling and theory may aid in the identification of the key mechanisms underlying the behavior of the system as a whole. The primary focus on his research is biochemical kinetics, protein homeostasis and protein folding diseases.

Career

Education

Dr. Schnell received his initial training in biological science from Universidad Simón Bolívar in Venezuela and doctorate in mathematical biology from the University of Oxford, England, United Kingdom. He pursued his doctoral and postdoctoral research under the supervision of Philip Maini, FRS in the Wolfson Centre for Mathematical Biology at the University of Oxford.

Professional Work

From 2001-2004, he was Junior Research Fellow at Christ Church (a college of the University of Oxford) and a Research Fellow of the Welcome Trust at the Center for Mathematical Biology in the University of Oxford. He was Assistant Professor of Informatics and Associate Director of the Biocomplexity Institute at Indiana University, Bloomington between 2004-2008. In 2008, he joined the University of Michigan as Associate Professor of Molecular & Integrative Physiology, a U-M Brehm Investigator in the Brehm Center for Diabetes Research, and Associate Professor of Computational Medicine & Bioinformatics at the University of Michigan.

Dr. Schnell is President of the Society for Mathematical Biology. He serves on the Editorial Board of Mathematical Biosciences,.[3]

Research

Dr. Schnell systematically investigated for the first time how the rate laws describing intracellular reactions vary as a function of the physico-chemical conditions of the intracellular environments. His work has focused to resolve the ambiguities in the quantitative analysis and modeling of reactions inside cells. He has also focused his research attention on deriving mathematical expressions to estimate enzyme kinetics parameters under different reaction conditions. He has systematically obtained equations to estimate kinetic parameters for the family of Michaelis-Menten reaction mechanisms and determined their region of validity for the initial enzyme and substrate concentrations. Dr. Schnell derived a generic expression, known nowadays as the Schnell-Mendoza equation, to determine the Michaelis-Menten constant and maximum velocity for enzyme catalyzed reactions following Michaelis-Menten kinetics using time course data.

In addition, Dr. Schnell has also extensive experience in developing multiscale models of developmental processes and cancer. His work has been highlighted in popular science magazines, such as American Scientist[4] (USA), Investigación y Ciencia[5] (Spain and Latin-America), Spektrum der Wissenschaft (Germany).

Teaching and Outreach

Dr. Schnell received the Faculty Award for Teaching Excellence from the School of Informatics at Indiana University in 2006. As a member the Hispanic and hidden disability communities, Dr. Schnell is actively promoting involvement of Hispanic, other minorities and disable people in science.[6] He is life member[7] of the Society for the Advancement of Hispanics/Chicanos and Native Americans in Science.
