Steven Schoenfeld's Summary

Specialties

My area of specialization is Analytical Chemistry (Chromatography, AA, FTIR, MS). I am

especially strong with UPLC methods development and SPME as a GC sampling technique.

The other area I have a strong background in is protein research (molecular biology,

BIAcore L1 sensor chip). I worked at a lab that studies lipid binding proteins and protein

domains.
