Jason D. Hofstein


Ph.D. Chemistry SUNY Stony Brook
B.E. Chemical Engineering Cooper Union


I earned my B.E. in chemical engineering from the Cooper Union in 1993, and from there went on to Stony Brook University, where I earned a Ph. D. in chemical physics in 1999. After a year as an editor at the Americal Physical Society, I took a position as the Director of Intermediate Chemistry Laboratories at Stony Brook University. In 2003, I was offered a position as a visiting professor of chemistry at Siena College in 2003, and I am now an associate professor in the chemistry and biochemistry department.

What I love about Siena:

Being a professor at Siena College provides me with the awesome opportunity to instruct students and help them develop the skills they will use based on their wants and needs. I consider it a responsibility to show any of my students, regardless of their major, that understanding chemistry and science is within their reach. This makes my role as a teacher rewarding as well as a very exciting challenge.

My Favorite courses to teach are:

  • CHEM 310: Thermodynamics and Chemical Equilibrium (Lecture)
  • CHEM 100/FCSE 100: Introduction to Forensic Science (Lecture)
  • CHEM 225: Analytical Chemistry Laboratory (Laboratory)
  • CHEM 105/FCSE 105: Criminalistics (Lecture and Laboratory)

Professional Experience:

Associate Professor, Chemistry & Biochemistry Siena College 2009 - Now
Assistant Professor, Chemistry & Biochemistry Siena College 2004 - 2009
Vist. Asst. Professor, Chemistry & Biochemistry Siena College 2003 - 2004
Dir. of Chemistry Labs, Chemistry SUNY at Stony Brook 2000 - 2003
Asst. to Editor, Chemical Physics American Physical Society 1999 - 2000
Lecturer, Chemistry SUNY at Stony Brook 1999 - 2000

Why I chose Siena:

Low student-to-teacher ratio; excellent teaching faculty; excellent research facilities

My current research:

· Analytical techniques of gunshot residue detection and classification
· Thermodynamics of hydrogen bonding in aprotic solutions
· Simple pulsed dye lasers for undergraduate research
· Forensic science course development
· Analytical chemistry laboratory development

My teaching philosophy:

One of my professional goals is to spark my student’s interest in science by using various mechanisms and approaches. Today science plays a central role in solving many of our current problems, including energy and environmental concerns. I have found students respond well to principles that are presented in the course from a perspective applicable to modern society or to their field of interest. Relating difficult thermodynamic or quantum mechanical principles to recent movies they may have seen, or video games they might play, are useful in bringing concepts home.
