Linda Avey


The age of ‘precision’ healthcare, where use of an individual’s metrics are used to target therapy and design preventive recourse, is still in its infancy, but Linda helped push it forward. 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. Those experiences motivated her to create new and disruptive research strategies.

Scientific Advisory Board


Harmit 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.


David Spiegel PhD

David attended Harvard University where he conducted research under the guidance of Professor Yoshito Kishi. After graduating from Harvard, David began in Yale University’s MD/PhD program. There he conducted graduate research in Professor John Wood’s laboratory focusing on developing synthetic approaches toward the phomoidrides. Following graduation from Yale, Professor Spiegel moved back to Harvard for postdoctoral studies under the guidance of Professor Stuart L. Schreiber. There he focused on developing an oligomer-based method for small-molecule synthesis to enable the rapid assembly of skeletally diverse small molecules starting from simple monomers.

David began as an Assistant Professor at Yale in June of 2007, was promoted to Associate Professor in 2011, and then to Full Professor (with tenure) in 2014. David has led the Spiegel Group’s research efforts in a number of successful directions, ranging from the development of antibody-recruiting molecules to fundamental studies of advanced glycation end-products.  He has also served as a consultant for International Flavors and Fragrances, Novartis Institute for Biomedical Research, Bristol-Myers Squibb, and Pharmaseq.  He has been recognized with various awards and honors, including the NIH Director’s New Innovator Award, the Department of Defense Era of Hope Scholar Award, the Ellison Medical Foundation New Scholar Award in Aging Research, the Novartis Early Career Award in Organic Chemistry, the Bill and Melinda Gates Foundation Grand Challenges Explorations Award, an Alfred P. Sloan Foundation Fellowship, and others.
