Assistant Research Scientist @Purdue University My research projects: Protein structure modeling, prediction, Protein structure Modeling from cryoEM data.
Very excited to share our new paper DAQ-score, just published in @naturemethods .
Our deep learning method can estimate the local quality of the protein structure model from cryo-EM data.
DAQ is available on Google Colab:

Paper:
https://t.co/V0RIjs9ZoT
The August update of DAQ-Score DB! It includes Cryo-EM protein model quality evaluations for 283,198 proteins. Figure is an example of a model with seq shifting error.

DAQ is easy to compute for str validation for your paper: https://t.co/oXoKmRF9Pv
We posted a new preprint, Prot-LAMBDA.
Unlike most protein language models, it is a pLM with an explicit encoding of protein structures. Strong performance in structure-related tasks including str prediction. https://t.co/IzGpgKtpGf
Please stop by my poster at M&M2026!

In May (5/6 2026) we gave a webinar introducing our EM web server. The recording is now available!
Highlighted 2 recent additions:
• DAQplugin: On-the-fly structure validation for ChimeraX
• CryoZeta: A heterogeneous str modeling for proteins and DNA/RNA
https://t.co/2V5tUnH6Yx
Our EM server Webinar recording is now available on YouTube!
I presented,
CryoZeta : Our new framework for cryo-EM structure modeling
DAQplugin : ChimeraX plugin for visualizing and analyzing DAQ scores for model quality assessment

Another new preprint of DMcloud, our cryo-EM modeling method for medium- to low-resolution maps. DMcloud uses local model fitting to place compatible protein or DNA/RNA models into enhanced EM maps. https://t.co/PdGAkGZNRK
Our recent preprint introduces DAQplugin, a ChimeraX plugin for interactive residue-wise validation of cryo-EM protein models. DAQplugin brings DAQ scoring directly into model inspection on your laptop. https://t.co/G4wZvFIdj9
We will host a ~30 min webinar introducing EM-server for cryo-EM structure modeling on May 6 (Wed) 12:30pm (Eastern Time). Will introduce DAQ-Score plugin & CryoZeta.

We’ve rebuilt our Protein Function Prediction server!
New:
• Domain-PFP: self-supervised, domain-aware function prediction
• GO2Sum: converts GO terms into UniProt-style functional summaries
All methods (PFP, Phylo-PFP, ESG) now in one interface.

🚀 First DAQ-Score DB update of 2026 is live!
Cryo-EM protein model quality evaluations now cover 266,577 protein chains.

🏁Check out also our New ChimeraX plugin! It lets you check DAQ scores during modeling!
https://t.co/q98zmpLoLq
DAQ for ChimeraX is now released! DAQplugin computes residue-wise DAQ scores directly in ChimeraX. By comparing cryo-EM maps with atomic models, users can quickly identify potential problems, such as sequence shifts or incorrectly assigned residues.
