Unsupervised Model Construction in Continuous-Time
Many of the advancements reconciling individual- and group-level results have occurred in the context of a discrete-time modeling framework. Discrete-time models are intuitive and offer relatively ...

My first paper as an Assistant Professor at UC Davis is out in the journal SEM!
In the paper, we introduce a continuous-time extension to the GIMME model implemented in OpenMx. It uses iterative tests of modification indices to construct group- and person-specific dynamic networks!

Wanted to announce that I will be recruiting graduate students this year in Quantitative Psychology here at UC Davis. If you are or know of any undergrads who are interested in dynamical systems and network analytic methods, please send them my way or get in touch!

Have to ask while Starter Pack Mania is at its apex:
Have we made a Quant Psych starter pack? If we have, I’d love to be added but if not perhaps we can get one going.

Lots of new followers today thanks to @omidvebrahimi.bsky.social!
Hello everyone! I'm an Assistant Professor at @ucdavispsych.bsky.social.
I'm a quantitative psychologist studying dynamic network models in discrete- and continuous-time and how we can find commonalities in person-specific dynamics.

We have a new preprint!
I'm excited to share recent work related to modeling multiple-subject, multivariate time series.
We extend the multi-VAR framework to allow for data-driven identification and penalized estimation of subgroup-specific dynamics.

Hi folks!
Sharing a pre-print that we just submitted from my dissertation work.
We adapted and extended the GIMME framework for identifying group-level structure in person-specific dynamics to the continuous-time framework via modification indices

Successfully defended my dissertation.
I’m a doctor now!
Got knighted by my advisors, Sy-Miin Chow and Peter Molenaar with an engraved sword gifted to my by Alexis Santos.
Lots of folks to thank but never enough space in these character limits.

Lots of exciting news in the coming months. Stay tuned!
First up, our new paper just came out with Sy-Miin Chow,
@sachaepskamp.bsky.social, and Peter Molenaar for fitting N = 1 graphical VAR models and using cluster-based methods to identify subgroups of people who share similar dynamic patterns.

Recent years have seen the emergence of an “idio-thetic” class of methods to bridge the gap between nomothetic and idiographic inference. These methods describe nomothetic trends in idiographic pro...
