Lassogen, Inc.

Lassogen was founded in 2019 to unlock the full potential of lasso peptides as a new therapeutic modality for diagnosing and treating some of our most intractable health challenges.

Lassogen is the result of a convergence of technical advances that have opened the door to a vast, new, untapped source of novel medicines.

Realizing our grand vision requires an outstanding team with the right skills, experience, and shared passion to turn great ideas into real cures.  It's all about the people.   We are Lassogen...


Founding Management

Mark J. Burk, PhD

President & CEO

Kent S. Boles, PhD

Head of R&D

A serial entrepreneur, Mark has over 30 years of experience in academia and biotech/pharma at both small and large companies. He has built high performance teams, new technologies, platforms, IP portfolios, and product pipelines, from ideation to commercialization.   Mark  earned a PhD in organic chemistry from Yale University and performed postdoctoral work at MIT with Nobel laureate Barry Sharpless.  Mark has published over 80 peer-reviewed papers and is an inventor on over 300 patents.  Mark has received many honors and awards and has presented over 300 lectures at major conferences and universities.  For more information, see:  https://www.linkedin.com/in/markjburk/

Kent is a full stack synthetic biologist and immunologist with over 20 years of experience in automation and DNA workflows. As a postdoctoral researcher at University of Oxford and Washington University,  he discovered several immuno-oncology targets and later established a phage display core targeting nanoparticles with peptides. Kent was also the technical lead for the Digital to Biological Converter at Synthetic Genomics, the world’s first fully automated platform to produce biologic compounds from digital DNA designs. The device brought together synthetic biology workflows with bioinformatics and engineering disciplines. https://www.linkedin.com/in/kentboles/

Academic Co-Founders

Prof. Douglas Mitchell, PhD

Univ. Illinois, Urbana-Champaign

Lassogen Advisor

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/


Prof. Tracy Handel, PhD

Univ. California, San Diego

Lassogen Advisor

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/
