In parallel, we are deeply committed to training the next generation of scientists by providing hands-on experience across these disciplines, fostering a collaborative environment where students learn to think critically, work across fields, and contribute meaningfully to therapeutic innovation.<\/p>\n\n\n<h3>Covalent Drugs\u00a0<\/h3>\n<p>Covalent inhibitors have (re)emerged as powerful tools in drug discovery due to their ability to achieve high potency and prolonged target engagement through irreversible binding. They are particularly valuable for targeting shallow or transient binding pockets and have shown clinical success in areas such as oncology and infectious diseases. We seek to better understand the power of covalent drugs and develop deeper understanding for their characterization and optimization.<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/pubs.acs.org\/doi\/10.1021\/acs.jmedchem.5c01661\">Profiling and Optimizing Targeted Covalent Inhibitors through EGFR-Guided Studies<\/a><em>.

By integrating structural biology and modeling into established targets, we aim to prioritize certain design strategies leading to more efficient and targeted synthesis if highly-active compounds.
