The questions and ideas that keep us busy and motivated
Investigating membranes + membrane protein biology and dynamics in the context of human health
We are interested in interactions with and transport/communication across the plasma membrane including the actions of antimicrobial peptides, ion channels, and transport proteins. Our investigations leverage expertise and experience in bioengineering, cell biology, and quantitative fluorescence microscopy with project outcomes relating to regenerative medicine, rational design of peptides, and creative microscopy approaches and analyses, all towards developing improved therapeutic approaches for a variety of human diseases and conditions.
These goals are advanced by three active areas of current research
Investigations of protein-protein interactions between cardiac voltage-gated potassium channel proteins hERG and KvLQT1
We study and quantify the location, mobility, and interactions between these ion channel subunits in model cellular systems to address whether protein-protein interactions and phosphorylation play a role in arrhythmias and sudden cardiac death.
Mechanisms of adult stem cell resistance to the chemotherapeutic agent methotrexate
Adipose-derived adult stem cells are less susceptible to methotrexate than other stem and non-stem cell types. We aim to determine the mechanism(s) of their resistance in efforts to develop therapies to help both stem cells and normal, differentiated cells survive while cancerous cell types are affected and eliminated during treatment.
Characterization and design of antimicrobial peptides
In collaboration with the Elmore Lab at Wellesley College, our shared objective is to identify factors critical for systematic, novel antimicrobial peptide design while also furthering methodological innovations for considering peptide interactions with membranes, cellular localization, and comparisons of activity in prokaryotic and eukaryotic cells.
