Passion for discovery

Dedication to science

Hope for cures

Commitment to community

Perlara was originally founded as Perlstein Lab, PBC in February 2014. Perlara, PBC is a biotech startup and Public Benefit Corporation based in the Bay Area that is on a mission to accelerate the discovery of cures for specific diseases and uncover underlying mechanisms that enable the development of treatments that work across a range of diseases and individuals.

Perlara scientists and our PERLpartners™ are on the PerlQuest™ Ark mapping and navigating the Genetisphere. With our Perlara Platform, we launch PerlQuests to find treatments for specific diseases and a growing treasure trove of gene modifiers to apply to gene expressions and interactions across diseases.

We are a diverse team with expertise in genetics, pharmacology, cell biology, data science and automation. We share an enthusiasm for scientific discovery and a commitment to transparency and engagement.

She’s the co-founder of 23andMe, the leading personal genetics company. 23andMe was chosen as Invention of the Year in 2008 by TIME magazine and has been the subject of many in-depth articles and media interviews. Linda’s current start-up is We Are Curious, Inc., which she co-founded in 2011 with Heather Anne Halpert and Mitsu Hadeishi. Curious is an online platform where diverse data from sensors, wearables, trackers, apps, social media, biometrics, and other sources of personal data can be gathered, explored, and shared. Curious provides analytics, a social graph, and an infrastructure for people to get the most out of that data. Prior to her start-up experience, Linda spent over two decades working in the pharma/biotech and biomedical research field, directly interfacing with scientists who sequenced the human genome to protein biochemists mapping the proteome.

Scientific Advisory Board

Harmit Malik, PhD
Professor, Fred Hutchison Cancer Research CenterHarmit Malik PhD

Harmit Malik grew up in the city of Bombay in India. He attended the Indian Institute of Technology where he received a degree in Chemical Engineering. He then joined the PhD program in Biology at the University of Rochester, under the mentorship of Tom Eickbush, studying the evolutionary origins of retrotransposable elements. He then worked on the evolution of centromeric histones and other assorted problems in Steve Henikoff’s lab, funded by a postdoctoral fellowship from the Helen Hay Whitney Foundation. He decided to stay at the Hutch after his postdoctoral term and started his lab in fall of 2003. Harmit is interested in a variety of problems that could all be classified under the genetics of evolutionary conflict. He studies rapidly evolving proteins as a hallmark of this kind of conflict, hoping to better understand the molecular nature of the conflict, as well as uncover previously unrecognized sources of conflict. His lab is currently working on several rapidly evolving projects—including centromeres and heterochromatin, nuclear import and variant histones, and innate defense strategies against retroviruses.
