Prof. Douglas Mitchell, PhD
Univ. Illinois, Urbana-Champaign
Prof. Tracy Handel, PhD
Univ. California, San Diego
Professor Mitchell is a recognized leader in the fields of genome mining and natural products research, with an emphasis on understanding the biosynthesis, structure, and function of lasso peptides. Doug wrote the algorithm called RODEO, which was trained by machine learning and unexpectedly revealed the broad prevalence and sequence diversity of lasso peptides in nature. Doug and Lassogen are collaborating on various programs aimed at implementing cell-free technology for lasso peptide discovery and optimization. PhD: UC Berkeley; Post-doc: UC, San Diego School of Medicine. https://www.linkedin.com/in/douglas-mitchell-01b8159/
Professor Handel is one of the foremost experts in the area of protein structure and function, with an emphasis on G protein-coupled receptors and the chemokine receptor subclass. Tracy and her team determined some of first structures of chemokine receptors bound to ligands and has gained great insight into the structural requirements for binding and modulation of chemokine function. Tracy and Lassogen are collaborating on the design of novel lasso peptides as high affinity ligands for chemokine receptors and other GPCRs. PhD: California Institute of Technology; Post-doc: DuPont Merck. https://www.linkedin.com/in/tracy-handel-06426a40/
