Marcus J. Jellen

OVERVIEW

Marcus Jellen is a Technical Advisor at Haley Guiliano, where his practice focuses on drafting and prosecuting patent applications for pharmaceutical, biotechnology, and other life science clients.

Prior to joining the firm, Marcus worked as a Synthetic Chemist at Element Biosciences where he improved Next-Generation Sequencing systems by developing new dye scaffolds with specific photophysical profiles and improved water solubility. His work there also involved exploring unprecedented reactions on dyes that yielded multiple patents. Additionally, Marcus spent time at Intel Corp. where he worked as a chemical-mechanical-planarization engineer. While there, his responsibilities included process development across several layers and technology nodes and sustaining production lines to meet company goals.

Marcus completed his Ph.D. at the University of California, Los Angeles, where he studied organic chemistry. His doctoral research focused on the design and synthesis of stimuli-responsive complex small molecules and materials. Using synthetic and computational methods, he developed the most efficient molecular spur gear to date and outlined strategies to observe long-sought-after gearing behavior in molecules. Marcus also developed the first amphidynamic material featuring dynamic organic radicals and alongside researchers at Bowling Green University, disclosed its utility for Quantum Information Science. Additionally, Marcus gained expertise in solid-state NMR spectroscopy and other forms of materials characterization allowing him to collaborate with multiple researchers around the globe.

Before his Ph.D., Marcus obtained his B.S. degree in chemistry with a minor in physics from the University of Wisconsin – Milwaukee in 2015. While there, he researched the asymmetric synthesis of oxindole-based natural products such as Horsfiline. He also derivatized benzofuran-based NSAIDs destined to be opioid replacements for pain mediation.
