Upon returning to NJ and successfully transitioning into the M.D./Ph.D. program, Jimmy joined the Freundlich group with an interest in broadening his experience in synthesis and developing small molecules against Mtb and other multi-drug resistant bacteria. From the medicinal standpoint, Jimmy has published papers concerning skull base surgery, but he is still open-minded about his ultimate career choice.
Alexander L. Perryman, Ph.D., is a senior researcher (Research Teaching Specialist III) in the lab, with extensive training in computational methods in drug discovery and in the biochemical mechanisms of multi-drug-resistance in infectious diseases. He is a member of the Center for Emerging & Re-emerging Pathogens, in the Department of Pharmacology, Physiology & Neuroscience. Alex started performing research in Professor Cleo Samudzi's X-ray crystallography lab as a freshman in the undergraduate Biochemistry program at the University of Missouri-Columbia ("Mizzou" or MU). He then became a Beckman Scholar in Professor Thomas P. Quinn's protein structure & radiopharmaceuticals lab at MU. He received his Ph.D. in Biomedical Sciences from the University of California, San Diego (UCSD) School of Medicine (Pharmacology Department) as a Howards Hughes Medical Institute fellow in H.H.M.I. Principal Investigator J. Andrew McCammon's lab. As a graduate student, Alex used Molecular Dynamics simulations to (a) predict a mechanism of multi-drug-resistance for "super bug" mutants of HIV protease, (b) to predict the existence of allosteric binding sites on the surface of HIV protease and then (c) to test the utility of exploiting that allosteric relationship. These predictions are now supported by an ever-growing body of experimental evidence. He also helped create the "Relaxed Complex Scheme," which was one of the first methods to incorporate the flexibility of the target protein into docking studies of potential drug-like compounds. He conducted post-doctoral research at the California Institute of Technology ("Caltech") as an Amgen fellow in the Division of Biology. He then became a Research Associate in Prof. Arthur J. Olson's lab at The Scripps Research Institute (TSRI), where he ran the day-to-day operations of the FightAIDS@Home project (the largest computational drug discovery project devoted to HIV/AIDS, which runs on IBM's World Community Grid). He also designed, led, and ran the day-to-day operations for the largest computational drug discovery project ever performed against malaria, the GO Fight Against Malaria project, also on IBM's World Community Grid. GO FAM involved screening 5.6 million compounds against 22 different classes of drug targets (including targets from Mycobacterium tuberculosis, as well). GO Fight Against Malaria was the first academic project to ever perform over 1 billion different docking jobs. His experience is highlighted by over 28 publications and one US patent.
In the Freundlich lab, Alex has broadened his experience by becoming an expert at developing and applying machine learning models and other ligand-based techniques to advance Mtb research, as well as projects against the ESKAPE pathogens. He has also created several machine learning models to help address key shortcomings in chemical tool discovery and drug development (such as metabolic stability, cytotoxicity, and solubility). For a change, Dr. Perryman has also been getting his hands wet--purifying proteins and performing enzyme inhibition assays, to help test his new computational predictions against Mtb targets.
