Associate Professor at RIT investigating galaxy evolution. Co-lead of the COSMOS Collaboration. Passionate about public outreach, science communication, and inclusivity. Currently working on all things JWST (especially, COSMOS-Web, CEERS, NGDEEP, PRIMER).
Our release includes an interactive viewer where you can explore the images, display the spectroscopic redshifts (Khostovan et al. 2025) and information from the photometric catalog (including their full SED, photometric redshift, the cutout images in each filter, and the zPDF).

Then, Harish et al. describe the MIRI data reduction and present the galaxy number counts. arxiv.org/abs/2506.03306

Along with the data, we have released three papers describing the data reduction and catalog process.
First, Franco et al. describe the NIRCam data reduction process and challenges for handling a dataset of this size. arxiv.org/abs/2506.03256

It's finally here! We've just released all of our COSMOS-Web images and catalogs, along with an interactive viewer where you can explore the data! Check it out at: cosmos2025.iap.fr

My PhD student Rohan Pattnaik's first paper on the machine learning tool he developed to automatically measure redshifts directly from galaxy spectra, SpecPT, is now out. The results are have surpassed my expectations and I can't wait until we extend this to other datasets!

Ok, I do love that with very little effort, I have a feed for Cat pics!
