I know I’ve been looking at compound discoverer too long this week because I had several dreams about FISh scoring last night

I’m especially excited though because I’m learning new things! First time working with complex matrices, pesticide residues, and learning how to do the qNTA modeling. At the same time I’m continuing to develop my expertise in HRMS and NTA. This is exactly what I wanted out a postdoc

I’ve been working on the methods since September and finally started experimentation this week on site at the FDA. Weird timing to be starting at the FDA for sure….

I’m really excited about this project I’ve been working on in collaboration with the FDA and EPA. I’m developing qNTA methods to look at pesticide residues in various food matrices.
