FOCUS on RESEARCH
Sarah Clippinger in Dr. Michael Greenberg's Lab is culturing human stem cell derived cardiomyocytes to model heart disease.
Dr. Weikai Li's lab is working on structural and biochemical studies of membrane proteins supporting blood coagulation.
Dr. Timothy Lohman's lab is working on equilibria and kinetics of DNA-protein interactions; DNA motor proteins (helicases) and helix destabilizing proteins.
Dr. Michael Greenberg's lab focuses on generation and transduction of forces by molecular motors, with an emphasis on human disease.
Dr. Roberto Galletto's lab is working on the roles of DNA helicases in maintaining telomere structure.
Dr. Greg Bowman's lab combines computer simulation and biochemical experiments to understand the role of proteins' conformational heterogeneity in antibiotic resistance and vision.
Dr. Peter Burgers' Lab studies DNA replication and DNA damage response mechanisms in yeast, using a combination of biochemical, biophysical and genetic approaches.
Dr. Eric Galburt's lab focuses on mechanistic and single-molecule studies of transcription initiation in eukaryotes and pathogenic bacteria.
Dr. Linda Pike's lab is working on mechanism of action of growth factors; polyphosphoinositide metabolism.
Congratulations to Dr. Jim Janetka, whose promotion to Professor was officially approved on September 11, 2020.

Dr. Natalie Niemi joined the Department on July 1, 2020, as an Assistant Professor on the Investigator Track. Her lab will investigates how mitochondria are built, regulated, and maintained across physiological contexts. We blend biochemistry, systems biology, and physiology to understand mechanisms of mitochondrial regulation and how they influence metabolism and organellar function. Using insights gained from our molecular studies, we aim to understand how mitochondrial dysfunction contributes to mammalian pathophysiology, with the long-term goal of translating our discoveries into new therapeutic options to restore mitochondrial function in human disease.

Dr. Alex Holehouse joined the Department on January 1, 2020, as an Assistant Professor on the Investigator track. His lab will explore how intrinsically disordered protein regions confer biological function and how this goes wrong in disease. The lab integrates physics-based models (all-atom and coarse-grained simulations) with informatics and machine learning to develop sequence-specific predictions. They then test those predictions either within the lab or with collaborators around the world.

Jhullian Alston (JJ) is a fourth-year graduate student in the Biochemistry, Biophysics, and Structural Biology (BBSB) program. He is completing his Ph.D. thesis work jointly between the labs of Dr. Andrea Soranno and Dr. Alex Holehouse, where he combines computational biophysics with single-molecule fluorescence spectroscopy to understand how intrinsically disordered regions within a protein can affect interactions with both proteins and nucleic acids.
Jhullian joined the BBSB program after receiving his B.A. in Biology from The University of Maryland, Baltimore County where he was a Meyerhoff and MARC Scholar. Prior to starting his Ph.D. work, Jhullian had a diverse research background, studying nerve injury after radical prostatectomy, developing mouse models of prostate cancer, using CRISPR to develop fusion proteins in P. falciparum and C. elegans, and investigating the effects of O-GlcNAcylation.

On June 12, 2020, Ms. Megan Cohan and Dr. Jonathan Lin were awarded the 2020 Ceil M. DeGutis Prize in Chemical Biology/Medicinal Chemistry.
Ms. Cohan presented her research entitled “Small but mighty! Intrinsically disordered domains as key regulators of bacterial processes” followed by Dr. Jonathan Lin who presented his research entitled “The Role of NAD+ in Retinal Neurodegeneration”.
