This characterization of the data allows us to outperform complex machine learning architectures with simple linear regression models for prediction of emergent phenomena (e.g., hydration free energy, solvent-mediated reactivity). (4/n)

(5/5) Work done in collaboration with @MadVictorZ, Benjamin Laubach (MSU/Dow), and Ivan Castillo (Dow).

(4/n) Once the data has been projected to a linear (Euclidean) space, we can safely apply methods that make this assumption (e.g., PCA)! This is demonstrated in two real world examples where we see dramatic improvements in both classification and dimensionality reduction.

Excited to share our work “Data Analysis using Riemannian Geometry and Applications to Chemical Engineering”. We focus on the geometric analysis of symmetric positive definite (SPD) matrices in anomaly detection. Links: adsmithphd.com & bit.ly/3wAgLsn 🧵1/n

I am applying for faculty positions this year and will be speaking at #AICHE2021 in Boston. My talk will focus on applying topology, geometry, and data science to chemical engineering systems. Stop by if interested! Details: adsmithphd.com #AcademicTwitter #ChemE

Prospective PhD students - check out the UW-Madison Chemical and Biological Engineering (@UWMadCBE) virtual info session next Monday! We'll present an overview of the department, opportunities for Q&A with current students and faculty, and advice on preparing your application.

Today's UW CBE Computing Seminar features Dr. Yili Qian, postdoctoral researcher from the Department of Biochemistry. Yili will share his work developing mathematical models biological systems. Join us today at 1:00 PM CST via Zoom. Seminar details in attached flyer.

@MadVictorZ @PhilipTominac @McMasterU @UWMadison Thanks for being such a great mentor (and wordsmith) @PhilipTominac!

@kmnitesh05 @LatinXChem So from this we could infer that co-solvents that disrupt water-water interactions (similar to what we see in DMSO) would be best for increasing the reactivity of fructose. Consequently, we should avoid co-solvents that cause water to form large clusters in the system (like THF).

@kmnitesh05 @LatinXChem (1/2) Thank you for the question! In the example for THF and DMSO (fructose reactant) we know from experiments that THF yields the smallest reactivity increase, and DMSO the highest. We also see large topological differences in these particular co-solvent systems with the EC.

Hi @LatinXChem, I'm excited to share my work titled "Topological Data Analysis: Applications in Molecular Simulation". Feel free to reach out with any questions! #LatinXChem #LatinXChem2021 #LXChemEng #Eng005 High Res Version Here: drive.google.com/file/d/1GHLXUP…
