Summer mini symposium on zebrafish development at SF State

20 Jul

Last week, my colleague Karen Crow and I hosted two amazing speakers from the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany.

Caren Norden talked about “Using zebrafish retinal development as a model to understand the interplay of cell biology and mechanics during morphogenesis: From cells to tissue”

Nadine Vastenhouw talked about “The role of chromatin in repression and activation of the zygotic genome”

We invited colleagues and students from the Biology Department and provided lunch for everyone. There were around 70 people, most of them students.

The talks were great! Thanks, Nadine and Caren for visiting SF State!

Students in the lab

15 Jul

I have 10 undergraduate and one graduate student in the lab this summer. It is fun!

I’ll soon make a page with names and pictures.

Paper on imperfect drug penetration and drug resistance out in PNAS

18 May

I am very excited to announce that our paper entitled: “Imperfect drug penetration leads to spatial monotherapy and rapid evolution of multidrug resistance” is out in PNAS.

Stefany Moreno-Gamez and Alison Hill are co-first authors on this paper. Both of them have contributed to every aspect of the paper.

Daniel Rosenbloom, Dmitri Petrov and Martin Nowak are the other co-authors on the paper.

Two-minute movie explains the main point of the paper

I made a short movie (2.5 minutes) to explain the main point of the paper:

The story behind the paper

I wrote a blog post for Haldane’s Sieve about how we started the collaboration that let to the paper. Here is the link.

Paper on sweeps in HIV wins honorable mention Omenn prize

19 Mar

The Gilbert S. Omenn Prize is awarded by the International Society for Evolution, Medicine, and Public Health for best article published each year on a topic related to evolution in the context of medicine and public health. The prize committee consisted this year of Sarah Tishkoff, Joe Alcock, Noah Rosenberg, and Alison Galvani. The real prize for 2014 went to, “Escape from bacterial iron piracy through rapid evolution of transferrin” by Matthew Barber and Nels Elde from the University of Utah. But my paper together with John Wakeley and Sergey Kryazhimskiy won an honorable mention :-)

Look here for the paper and here for a 3 minute explanation of the results.

Paper on ant slaves accepted in Journal of Evolutionary Biology

17 Sep

In 2009 I made a trip to the USA to collect ants in New York and West Virginia to study their small scale population structure. Now, 5 years later, the paper is finally accepted for publication in the Journal of Evolutionary Biology!

The accepted version is also posted on the arXiv.

Short video about PLoS Genetics paper

3 Jun

I made a video about selective sweeps in HIV.

As always, it was a lot of fun to make the movie and it took much more time than I planned.

I used two apps to make the video, iMotionHD on my iPhone and iMotion remote, on a second iPhone. For editing and adding the voiceover I used iMovie and a simple headset with microphone. I bought music from MelodyLoops.com.
