Ronald A DePinho

My sketch of Ronald A DePinho who together with Norman Sharpless, proposed the Stem Cell Theory of Aging.

Robert M. Sapolsky

My sketch of Robert M. Sapolsky who first linked aging to stress via the Glucocorticoid Cascade Hypothesis of Aging.

Thomas Johnson

My sketch of Thomas Johnson who first defined the AGE-1 gene.

Elizabeth Blackburn

My sketch of Elizabeth Blackburn who first discovered telomerase.

David Sinclair

My sketch of David Sinclair who discovered the possible role of resveratrol in aging.

Leslie Orgel

My sketch of Leslie Orgel who first propounded the error catastrophe theory of aging.

I got brave and decided to try sketch teeth and a smile, but didn't do so well. Otherwise, I think I did better than usual. I left lines off the nose, and tried to work on shading more. Shading really is essential. I almost feel like I need to go back to practice sketching objects before continuing with portraits.

Matt Kaeberlein

My sketch of Matt Kaeberlein who, as I read today, proposed that the TOR and Sch9 kinases regulate longevity in yeast. Dr. Kaeberlein is a researcher at the University of Washington Pathology Department.

As for the sketch, well one day I will learn how to draw teeth and a proper smile, but as for right now, this is the best I can draw.


Also, this is day 200 of this project.

Coleen Murphy

My sketch of Coleen Murphy who discovered age regulating genes downstream of daf-16.

Apologies in advance to Dr. Coleen Murphy, if you see this, I wish I could draw better than I do now, but please know, this is my best effort.

Francis Bacon

My sketch of Francis Bacon.

Andrea Bodinar

My sketch of Andrea Bodinar who found that telomerase extends replicative life-span of human cells.

My sketch of George C Williams who established antagonistic plieotropy as a theory of aging.

Denham Harman

My sketch of Denham Harman who proposed the free radical theory of aging.

Peter Medawar

Peter Medawar who first proposed that aging occurs due to genes expressed after reproduction and thus escaping the reach of natural selection.

Leonard Hayflick

Leonard Hayflick who discovered that cells have a limited replicative lifespan known as the Hayflick limit.



(He doesn't have a scar there, I just messed up the drawing, sorry Dr. Hayflick)

Matt Meselson

Matt Meselson talked at UNC today and will now study aging in rotifers.

Richard Weindruch

My sketch of Richard Weindruch who works on caloric restriction and aging.

Roy Walford

My sketch of Roy Walford who advocated caloric restriction for health and longevity.

Michael R Rose

My sketch of Michael R. Rose, researcher in experimental evolution and aging.



Sorry, the bottom half is dark because the sheet of paper had a fold in it.

Cynthia Kenyon

I sure wish I was better at portraits so I could do a better job of drawing my heroes. Cynthia Kenyon found daf-2 and daf-16's role in lifespan.

Clive McCay

My sketch of Clive McCay, the first to link calorie restriction with longevity, and the father of the modern science on aging. This is also my first profile sketch.
