Short term postdoc position open at SFSU

Come join us in San Francisco!

NIH / NSF funded postdoc position at San Francisco State University to work with Dr Pleuni Pennings in the CoDE Lab.

We are looking for a postdoc who can work on two different projects on viral evolution. One project is in collaboration with Dr Zandrea Ambrose and Dr Philana Lin from the University of Pittsburgh. The other project is in collaboration with Dr Adi Stern in Tel Aviv.

Both of the grants are nearing their end, which is why we are advertising only a short term opportunity (1 year of funding). This is a great opportunity though because there is great data available and there is a possibility of writing / contributing to two papers.

Preferred qualifications:

I am looking for someone with experience and interest in several of the following domains: evolution, virology, bioinformatics (next-gen sequencing data) and statistics. If you are interested in linkage and recombination, this would be a really cool project for you!

The preferred candidate will also have an interest in / experience with one or more of the following: teaching, working with students from groups who are traditionally underrepresented in research, outreach (e.g., writing, social media, video).

The preferred candidate will have experience with writing clear / understandable scientific prose as evidenced by a writing sample.

I’d be very happy to see applications from people who have left academia and are interested to come back. If you are not sure if you qualify, please reach out!

I hope to find someone who can start soon (Nov or Dec 1st 2021).

Why this is a great opportunity:

These are two cool projects in a productive lab (see my Google Scholar profile). You can expect to get several papers out of this short postdoc.

You will be part of a diverse lab and department of biology.

You will be working on an exciting project that bridges virology and evolutionary genetics and that could help us understand TB and HIV are such a dangerous combination.

You will be able to contribute to training of students of diverse backgrounds.

You will get the opportunity to work with people at the University of Pittsburgh and the University of Tel Aviv.

In the CoDE lab, you will work in a supportive environment where research is important, but papers are never more important than people.

Appointment:

Funding is available for one year. An extension will be possible if we are lucky enough to get new funding for the lab. The starting salary is $57,000 per year.

How to apply:

Send a 1-2 page cover letter, your CV, a paper (or draft) written by you, and names and email addresses for three references to pennings@sfsu.edu. Only pdf’s please!

Deadline:

I will start looking at applications from Oct 23th, 2021 and hope to hire as soon as possible after that.

New preprint and new video on how HIV evolves drug resistance

Together with Alison Feder (UC Berkeley) and Kristin Harper (freelance medical writer) I have written a manuscript on HIV drug resistance evolution on triple-drug therapies.

Triple-drug therapies were introduced in the 1990s to stop the evolution of drug resistance, but especially in the first years after their introduction, drug resistance evolution still happened often in patients on these treatments. How could this be? Have a look at our video and preprint!

The video was made by Dr Sarah Engelhard. Contact her if you would like to create a video for your paper!

We have previously made videos about related papers:

Lab visit to Tel Aviv

In February of 2019, 10 of us visited Adi Stern’s lab at Tel Aviv University. A blog post about the trip is on my blog.

Manuscript on HIV sweeps and clonal interference posted on BioRxiv

Kadie-Ann Williams and I posted a new manuscript on the BioRiv. It is 30 pages with 28 figures and a supplement of 118 figures! I guess we could call it an HIV drug resistance evolution picture book!

Muller plot showing clonal interference in patient 89.

Nowadays, drug resistance evolution is quite rare, but in the late 1990s, HIV populations within patients on treatment were undergoing soft sweeps, hard sweeps, clonal interference and other things. If you like sequence data, you’ll enjoy looking at our pictures!

Title: Drug resistance evolution in HIV in the late 1990s: hard sweeps, soft sweeps, clonal interference and the accumulation of drug resistance mutations

https://www.biorxiv.org/content/10.1101/548198v1

Abtract

The goal of this paper is to provide examples of evolutionary dynamics of HIV within patients who are treated with antiretrovirals. We hope that the figures in this paper will be used in evolution and population genetics classes. We show a wide variety of patterns, specifically: soft sweeps, hard sweeps, softening sweeps and hardening sweeps, simultaneous sweeps, accumulation of mutations and clonal interference.
