Why your time matters: Shrinking PhD cohorts and curtailed NIH Diversity Supplements mean fewer opportunities for strong applicants. Even a 10‑minute chat with faculty helps them hear the science, refine interests, and stay in the game.

Constraints are real: many campuses have hiring freezes, and exceptions are often possible. Funding can shift—today’s conversation can become a future match.

Unsure about hiring? Please join. The MME is a first step—not a commitment. Early conversations create options and keep pipelines moving.

Who are the scholars? Exceptional postbacs aiming for PhD/MD‑PhD/PharmD‑PhD—spanning a wide range of biomedical research interests (wet lab, computational, translational, clinical). Record interest: largest cohort yet (168).

What is the MME? A virtual, fast‑paced series of 10‑minute conversations where faculty meet recent grads for full‑time research roles and identify strong lab matches.

Play on Princess Bride, converting ROUS (rodents of unusual size) to VOUS (variants of unknown significance).

Amazing to be at the #CAGI7 conference. As a data PRODUCER, no less! Fascinating discussions about variants of unknown significance, and how to get rid of them. Sad they are almost always acronymized as VUS, and only once was it VOUS.

Did you publish with researchers outside your lab during grad school? Or published as faculty with a student not under your supervision?

I’m collecting examples of cross-lab collaboration in graduate training.

Please share your experience & this post!

Agentic Coding for Scientists (Dec 2025 edition)
YouTube video by Erick Matsen Agentic Coding for Scientists (Dec 2025 edition)

The era of coding agents is here. How do we approach this as scientists?

Wednesday Dec 10th at 9am PT I'll livestream an interactive demo of what I have learned (matsen.group/agentic.html) about how to leverage agentic coding to do rigorous science.

Dear Chancellors:
I'm writing with regard to the President's Postdoctoral Fellowship Program (PPFP) and the program's associated faculty hiring incentive.
As you know, for more than 40 years, PPFP has provided postdoctoral research fellowships, professional development, and faculty mentoring to scholars in all fields whose research, teaching, and service advance the academic and research missions of the University of California.
Since 2003, UC campuses that hire current and former PPFP fellows into ladder-rank positions have been eligible for a hiring incentive funded by the University that provides support for newly hired fellows for five years. Since the creation of the incentive, more than $162 million has been invested by the University to support PPFP faculty hires. This commitment has enabled our campuses to successfully recruit and retain outstanding faculty across a range of disciplines.
Given the myriad challenges currently facing UC - including disruptions to billions of dollars in annual federal support, as well as uncertainty around the state budget- reasonable questions were raised in recent months about whether the University could maintain the commitment to current levels of incentive funding. After considering a recommendation to sunset the incentive program due to these significant fiscal constraints, I consulted with all of you as well as faculty and campus academic administrators and systemwide Academic Senate leadership.

After learning more about the history and success of the program and weighing the thoughtful perspectives that have been shared, I have concluded that barring extraordinary financial setbacks, the PPFP faculty hiring incentive program will continue while the University continues to assess the program's structure as well as its long-term financial sustainability. As a result of our continuing consultation and review, there may be consideration of some changes to elements of the program including the total number of incentives supported, a number that has fluctuated significantly over the years, and how the awards are distributed among campuses. In the meantime, the University will continue to fund the PPFP faculty hiring incentive program and campuses may continue to take advantage of these incentives. We will have an opportunity to discuss any potential changes prior to adoption.
As we look to the future, I will continue to engage with faculty leaders, program stakeholders, and UC community members about this important program. I especially appreciate the thoughtful perspectives shared in recent weeks by Academic Council Chair Palazoglu and Vice Chair Scott, the Council of Graduate Deans, UC faculty members, and you as our campus leaders.

Sincerely,
James B. Milliken
President

Why we made Affinity free, and how we’ll keep it that way We’ve made Affinity completely free, empowering professional designers with studio-grade creative software, supported by Canva’s sustainable ecosystem.

I'm a longtime fan of Affinity Designer as an affordable Illustrator-killer for figures, and... it's now free?! www.canva.com/newsroom/new...
Highly recommended if you're sick of paying Adobe $. Maybe Canva can buy NPG too and get rid of the OA fees.

I wish more people would understand that real progress and innovation lies in using everyone’s potential, not just the few…that is where the real strength lies. The question is always, who is really benefiting from the status quo…let’s follow the money, shall we?
