anyway, i conduct human chemosensory research, specifically olfaction. past studies have included trigeminal irritation, reducing agricultural malodors, sexual orientation and perception of odors, etc. however, the PhD i work with likes to focus on human attraction via chemical signaling and i have found that my interest in that area has been increasing as a result. our current research involves genetic basis of odor perception.
