Mariana Mihalusova focuses on biotech and pharmaceutical investments, and is currently a Board Observer at Mythic Therapeutics and Ocelot Bio. Mariana brings to Venrock deep experience spanning the entire spectrum of drug development – from preclinical, to marketing approval, to lifecycle management – with a special emphasis on crossing the chasm from discovery to clinical validation.
Prior to joining Venrock, Mariana was Executive Director at Celgene Corporation, where she led global development for over a dozen drugs across hematology, oncology, inflammation/immunology, and neurodegenerative diseases – many of which she brought from development candidate nomination, through IND, to clinical proof-of-concept. Among the drugs in her portfolio were protein degraders (4th- and 6th-gen Aiolos/Ikaros, GSPT1), epigenetic modifiers (BETi, LSD1i), bispecifics (PD1xLAG3, CD47xCD20), and several CAR-Ts.
Mariana received her Ph.D. in Biochemistry from Harvard University, MBA from Harvard Business School, and Sc.B. in Biochemistry from Brown University.
I was born at Guide Dogs for the Blind in Marin as part of a G-litter (that is how I got my name – all my brothers and sisters have names that start with G). As a kid I was pretty distractible, so I moved to Dogs for Diabetics where they help type 1 diabetics with hypoglycemia. Some type 1 diabetics can not tell when their blood sugar is dropping, but I can smell it and would let them know so they did not go unconscious. I was about to go live with a teenage girl in Humboldt, but I got cancer and they had to operate, which meant that even though I was really, really good at my job, I could not do it. So now I follow Bryan wherever he goes. I’m the only dog at CloudFlare, so I get lots of belly rubs there, Kartik at Encoded is my buddy so I wiggle extra hard, and there are pretty good treats under the table at 10x. Sometimes I still help type 1 diabetics who don’t know they are going low in blood sugar. Boy are they surprised, but dude – I am that good…
