We work on fundamental questions of how cells are spatially organized applied problems in pharmacology and drug development. We ask how systems comprising microtubules, binding proteins and motors self-organize to promote cell division in frog eggs using microscopy and biochemistry. We work on the pharmacology of microtubule-targeting drugs, and to development new drug that combat cancer and inflammation by modulating innate immunity.

Dr. Apfeld is interested in the relationship between age-dependent cellular events and the lifespan of multicellular organisms. He is developing methodologies to make age a quantifiable observable in the nematode C. elegans, a well-studied organism of 703 somatic cells and an average lifespan of only two weeks.
The MacBeath lab is interested in identifying, characterizing, and perturbing large collections of proteins or protein domains as a first step in understanding how the cell exploits molecular recognition to regulate complex processes such as protein trafficking, intercellular communication, growth factor signaling, and apoptosis.
Laura Maliszewski, PhD joined HMS in September 2012 to manage the development of the Laboratory of Systems Pharmacology and the Harvard Program in Therapeutic Science. She served previously as an Officer in the Science and Innovation Network of the UK Foreign and Commonwealth Office, developing a broad portfolio of research collaborations in regenerative medicine, health economics and stratified medicine.
A key challenge in treating cancer is the wide range of effectiveness of current targeted therapeutics and the rapid development of resistance. I am trying to understand the mechanisms of drug responses and development of resistance using established breast cancer cell lines as a model system, since they mirror much of the behavior and heterogeneity of primary disease. I mainly study therapeutic drugs and ligands to receptor tyrosine kinases that modulate signaling through the ErbB family and the PI3K/AKT signaling pathways, which are particularly important in the development and treatment of breast and ovarian cancer. Ultimately, a detailed understanding of drug action will move us towards the development of a more personalized medicine, where tumors from each patient are analyzed on a molecular level so they can be treated with specifically tailored drugs or combinations that have been predicted to maximize efficacy and minimize the risk of resistance and toxicity.
I focus most of my work on proteins, rather than genomic measures, since they are both the key effectors of cellular function and the targets of the drugs. In my research I combine a variety of protein profiling methods, detailed measurements of phenotypic responses, and biochemical investigation into drug action. I analyze the data by statistical and computational methods to identify both predictors of drug response and the causal determinants drug sensitivities.
