Due to challenges with the current funding climate I won’t be reviewing clinical psych PhD applications this cycle. Sorry to miss out on the chance to mentor more amazing ECRs but hopefully things improve in the coming years.

I’m accepting applications for PhD students to join my lab in Fall 2027! Our work focuses on psychopathology, personality, classification and assessment, and using AI with intensive longitudinal methods to better understand mental health. See the lab site for more info: ringwaldlab.psych.umn.edu

Very cool new paper by @aleksakaurin.bsky.social, Mario Wenzel, @paulaphilippi.bsky.social using some of my K99 data: osf.io/preprints/ps... EMA studies often ask people how they feel several times a day. But when is a change bigger than measurement noise? And does the person actually feel change?

Reviewing applications for the Clinical Psych PhD at UC Berkeley this fall! We develop and test transdiagnostic treatments (soon including sleep-interfering media use) and study how to get them into real-world care. #ClinicalPsychology #PhD #SleepResearch #UCBerkeley

Excited this measurement manuscript is out. 6+year effort to address what we saw as limitations in how we use the PHQ-9. Work by @dawsonhaddox.bsky.social in collabo w my partner in (measurement) crime @eikofried.bsky.social. If you use PHQ for weekly assessment or symptom-level analyses, read this!

1/ @sadcatlab.bsky.social research "in press" at Journal of Consulting and Clinical Psychology. In 274 adults with 7 weekly measurements, we find that cognitive change in CBT predicts subsequent symptom change, controlling for time-invariant confounds + linear trends osf.io/preprints/ps...

Review of applications for tenure-track assistant professor position in @uarizona.bsky.social department of psychology (clinical area) begins Sept 1. Apply to join a fantastic department with truly wonderful colleagues and amazing students. arizona.csod.com/ux/ats/caree...

Excited to share a new Annual Review paper with @eriknook.bsky.social : "Large Language Models in Mental Health Research and Treatment." Here lay out what LLMs actually are and aren't, then take a census of how mental health research has used them so far, where it's heading 🧵1/n

Really proud of this work that came together as a pet peeve project of a few NSMD PhD candidates, and now ended up in New Ideas in Psychology. What are symptoms? www.sciencedirect.com/science/arti...

@lluaces.bsky.social with another banger! Thoughtful research design plus amazing writing equals another paper that will go on my lab’s required reading list.

Thrilled (really) to share recent evidence from our READY study led by @paulaphilippi.bsky.social w/ @aidangcw.bsky.social: "Minutes that matter: A microburst approach to adolescents' resolution of affect in response to daily stressors" 🧵1/9

Those of us who were trained at CTSA by Edna Foa will be very familiar with this. I love Exposure and Response Prevention (ERP)! I've licked the bottom of my shoe many times when working with OCD (and still do it 2x per year when I teach my undergrad and graduate courses on CBT). And much more...

Eiko is the best! If I didn’t have a family I’d quit my job and move to the Netherlands to work with him. Highly recommend these positions to any who might be interested!

What to do when #AI meets #OpenScience? @stokel.bsky.social spoke to me & other colleagues about this pressing issue for this @nature.com article. @drandreahoward.bsky.social @katiecorker.bsky.social @miriforbes.bsky.social @debruine.bsky.social

I had a great time giving my first conference talks, sharing my work on depression assessment and digital phenotyping at #APS26BCN! Grateful to my mentor (@depressionlab.bsky.social), my collaborators (Drs. Fried, Allen, Craske, Sachdeva, and many others), and everyone I met and learned from there.

1/ New paper 👀 TL; DR the COMET single session intervention (SSI) was superior in reducing depression, anxiety, and to a lesser extent improving well-being than a waiting control in college students. www.sciencedirect.com/science/arti...

Can less than 10 minutes daily on a mindfulness app improve the mental health of people of color exposed to discrimination? Based on our new publication in the Journal of Medical Internet Research (@jmirpub.bsky.social), the answer is yes! www.jmir.org/2026/1/e84328/ A 🧵:

We just got approved to hire a teaching professor in Quantitative Methods! This is the *very* rare tenure track teaching position at Berkeley. I'll be chairing the search committee. Official job ad coming later this summer!

NHS data should be driving innovation & improvement – it’s an amazing resource We just published the sequel to our 2021 "Road to Hell" paper on using NHS data for research... things are worse! Buckle up for a long 🧵about *how COMPLETELY mad* system is for accessing NHS data for research 1/20

Selecting an effect size for power analysis is hard. Many researchers fall back on Cohen's thresholds, but they have no empirical basis and vary wildly by field. Our new paper offers a better option: field-specific effect size distributions built from meta-analytic data doi.org/10.3758/s134...

Computationally formalising a verbal theory is an eye-opening experience because it forces you to openly state all the assumptions that the theory rest on

Most #EMA / #ESM studies rely on snapshots 📸 But experience is continuous! What if real insights live *between* measurements? 📉 Dr. Leonie Cloos used #m-Path’s continuous line item to collect affective intensity profiles in everyday life: blog.m-path.io/blog/blog-1/...

Hey friends, my new paper was just published in JAMA Psychiatry. I draw on biological species classification to sketch a new framework for psychiatric nosology. Brief summary follows below. Full text link: jamanetwork.com/journals/jam... 🧪 #PsychSciSky #MentalHealth

🚨 New paper out in Current Directions in Psychological Science, with @matnoc.bsky.social! We review recent advances in digital & computational methods for understanding, predicting, and preventing suicide.

Cuts to scientific research will have effects for years to come. @standupforscience.bsky.social has been an important voice connecting scientists & all of us. @cdelawalla.bsky.social leads that group, & her latest post is a call to action to restore funding 👇🏿👇🏼👇🏾👇🏻👇🏽 substack.com/home/post/p-...

Why do participants stop responding in #ESM / #EMA studies? 📱🔔 Average compliance is about 7️⃣9️⃣%, but that hides massive variation. Our new m-Path blog reviews predictors of response compliance: study design, incentives, participant traits, and time effects. 🔗 blog.m-path.io/blog/blog-1/...

Looking forward to expanding our small team a bit as the lab prepares for its 2nd year. We will be hiring 2-3 more volunteer, in-person RAs for our team to start in the fall. Details and application info are at our website. share.google/O1hvtUpPLIlp...

We at the @personalizedtx.bsky.social already knew how lucky we are to have the best postdoc (@juliayarrington.bsky.social), but lovely to see her recognized with @uarizona.bsky.social's Outstanding Postdoctoral Research award AND the Postdoc-as-Mentor award! postdoc.arizona.edu/news/congrat...

Great perspective piece on open-ended questions in ESM data by @bringmannlaura.bsky.social and colleagues that came out of this year's #MITNB meeting!

For instance: @claireecusack.bsky.social just submitted a paper today in which we show that discrete emotion states predict discrete avoidance behavior in SAD with *very* high accuracy. We know this, right? But now we can locate the phenomenon in *specific moments of time* à la JITAI concepts.

We're doing summerpsych.com again this year! PhD curious undergrads, come hang out at the CSI lab, help us push forward a project and develop your social science chops Applications are due March 1st:

I kept reading EMA studies claiming to test etiological theories of AUD, but I realized they never actually measured how people experience AUD in their daily lives. So we set out to see what we could learn with existing data. 1/19 journals.sagepub.com/doi/10.1177/...

If our theories have to do with people's daily experience then we really need to know how well we're measuring daily experience. So we need more of what Kevin's team is doing here! Just because your item has the right words in it doesn't mean you know what it measures, or how well.

We're hiring! The Computational Clinical Science Lab @ Yale is seeking a full-time lab manager/research coordinator to start in early summer 2026. For more information about the position and to apply: forms.gle/LtQwVgPUfaGk... Please share widely & consider applying!
