Alexander D. MacKerell, Jr. is an American biophysicist who is the Grollman-Glick Professor of Pharmaceutical Sciences at the University of Maryland, Baltimore (UMB) and the Director of the Computer-Aided Drug Design (CADD) Center at UMB. He is also the Co-Founder and Chief Scientific Officer of the drug design tech company SilcsBio. ^[1] In 2022, MacKerell was awarded the prestigious American Chemical Society Award for Computers in Chemical and Pharmaceutical Research. ^{[2] [3]}

Education and early career

Alexander D. MacKerell, Jr. began his post-secondary education at Rowan College of South Jersey, then Gloucester County College. ^[4] He obtained an associate degree in biology in 1979, then a bachelor's degree in chemistry from the University of Hawaiʻi at Mānoa in 1981. ^{[4][ citation needed]} MacKerell returned to New Jersey and enrolled at Rutgers University to work on a PhD under biochemist Regina Pietruszko, which he completed in 1985. ^{[4][ citation needed]} MacKerell held a postdoctoral fellowship at the Karolinska Institute under Rudolf Rigler for two years before moving back to the US where he worked on the development of the CHARMM protein force field under Martin Karplus at Harvard University. ^[5] MacKerell held a one-year appointment as a Visiting assistant professor at Swarthmore College in 1992-93, before accepting a position at University of Maryland, Baltimore in the Department of Pharmaceutical Sciences. ^[6]

Research

MacKerell's research contributions have been primarily in the field of computational biophysics, using modeling and simulation techniques such as Molecular dynamics or Monte Carlo to study the structure, function, and dynamics of biological macromolecules such as proteins, nucleic acids and lipids. MacKerell has been a leading developer of the widely-used CHARMM all-atom additive force field, particularly on parameterization, expanding it from primarily proteins in water in the early 1990s to include lipids, ^[7] nucleic acids, ^[8] carbohydrates ^[9] and organic small molecules. ^[10] Alongside the lab of Benoit Roux, the MacKerell lab has led the development of the CHARMM-based Drude polarizable force field, ^[11] which aims to address a key limitation of additive force fields, namely that each atom gets a single, fixed partial charge regardless of local environment. The group has developed or contributed to the development of online tools to make academic research more straightforward and accessible. These include CGenFF, ^{[12] [13]} FFParam ^[14] and DGenFF ^[15] for automated generation of force field parameters for novel small molecules (such as drug-like molecules), and the CHARMM-GUI webserver ^[16] used to generate inputs for various simulations. Besides force field development, the MacKerell group has also contributed to computational drug design in the development of the Grand-canonical Monte Carlo/ Molecular dynamics sampling method ^[17] upon which the Site-Identification by Ligand Competitive Saturation (SILCS) ^[18] technology is based. In 2008, he was named the inaugural Grollman-Glick Professor of Pharmaceutical Science at UMB. ^{[19] [20]} In 2022, the American Chemical Society awarded MacKerell the Award for Computers in Chemical and Pharmaceutical Research. ^[21]

MacKerell serves as an editor of the Journal of Computational Chemistry ^[22] PLOS Computational Biology, ^[23] and Proteins: Structure, Function, & Bioinformatics. ^[24]
