About Me

Most of my childhood and teenage years were spent thinking I would someday be an artist of some sort. Then I had two amazing teachers in biology who set me squarely on the path to becoming a scientist. After many many years of studying and training, I finally ended up with a PhD studying the genetics of heart development. I have since studied various biological systems at several different institutions.


Lately I’ve been pretty obsessed with learning a new set of skills in various types of woodworking. I previously did a lot of work with pan pastels and pastel pencils. I have also been done a fair amount of graphite pencil drawings, primarily commissioned pet portraits (I AM available for commission).

Most of my 3D digital work revolves around using the free and opensource Blender 3D modeling and animation software and GIMP, which is similar to photoshop. And I’ve done a bit of 2D digital drawing using tablets and computer.


Daniel DeWitt Brown, Ph.D.

I am currently a Research Scientist in the Institute for Precision Medicine at the University of Pittsburgh (in the Magee-Womens Research Institute), where I work on cutting edge methods to culture, expand, and cryopreserve cancer-derived organoids (currently from breast cancer).  

From 2012 to 2018 I worked in the Priscilla McAuliffe Lab at MWRI where I studied DCIS (ductal carcinoma in situ), a non-invasive form of breast cancer that is thought to be a precursor to invasive breast cancer. Until early 2012 I was a research scientist for Thermo Fisher Scientific. Prior to that I finished a post-doctoral position at Carnegie Mellon University in the lab of Dr. Veronica Hinman, where I studied the evolution of gene regulatory networks in organismal development (using sea stars and urchins as a model).  I was also formerly a post-doc at the National Institute of Environmental Health Science, working in the lab of Dr. Perry Blackshear where I studied the biology and genetics of brain development and function. I earned a BA in biology from Hendrix College and a PhD in the Program in Cell, Molecular and Developmental Biology at the University of North Carolina at Chapel Hill in the lab of Dr. Frank Conlon.

I also love talking, thinking, and writing about evolution. In this capacity, I created the Carnival of Evolution, a blog carnival devoted to the science of evolution. I have since passed the organization of the Carnival into much better hands: Björn Östman of Pleiotropy.


I am married to an absolutely amazing woman, Tamaryn Kelley Brown. She’s a mental health counselor, yoga enthusiast, and artist.

On a whim she decided to become a painter one random day and sold her first oil painting at her first showing. Last week she decided to try drawing. To the right is a sketch from her second day of learning to draw. She’s freakishly talented at everything she tries.





We have a pup named Bandit. Here’s a portrait I drew of him:

  1. ok, i love your site, but i totally cracked up about the “personal” paragraph about the cats. some weird genetic stuff goin’ on there, eh?

    miss you guys! i’m seeing a long weekend trip to PA early next year…..

  2. Dear Daniel,
    My name is Sabrina and I am creating a reading program which my sister is illustrating for me. When we started we didn’t realize that we need to have permission to draw pictures based on other people’s photographs. She drew a picture that was based off of a photo of a White-tailed Deer. The photo was posted to your old website in March of 2009. I was wondering if we could have your permission to use the photo as the basis for a drawing which will be used for commercial purposes as part of a reading/phonics program I am creating to sell on a website called TeachersPayTeachers. If not, I will ask her to start over with a photo that we own. I just want to make sure everything we do is legitimate. Thank you! P.S. If it is not your photo, would you please help me find out whose it is. I really appreciate any help you can give me!

  3. Have you ever published prints under the name Dan DeWitt? I have a sketch “Single Flower”. Looks like signed by Dan DeWitt (c) ’83. Is that yours? Just trying to find the artist…. Thanks, Jen

    1. I’m sorry, Jennifer, but it wasn’t me. I would have been 6 then, so I don’t think you’d want anything I drew back then 🙂 Unfortunately, all three of my names are pretty common together. There are thousands of Daniel Browns in the US. Good luck finding the real Dan DeWitt.
