irst of these involves understanding the photochemistry of kynurenine, a molecule found in the lens of our eyes, which transforms harmful ultraviolet (UV) light into harmless heat with incredible efficiency and speed. Understanding how this and related molecules function may influence the development of new sunscreens, UV-protective coatings, and dyes. The second example involves a collaborative project with Peter de Lijser’s laboratory in which we aim to determine the molecular pathways through which a family of reactive intermediates cyclize to form new molecules with complicated ring structures. As will be discussed, this reaction represents a new, environmentally friendly route towards making molecular structures that are commonly found in pharmaceuticals. Throughout my talk, I will highlight how the key computational approaches work as well as how I made informed decisions about the major approximations.</span></span><span class="m_8676270477640754736event-description"><span style="font-size:11.0pt;font-family:"Verdana",sans-serif;font-weight:normal"><u></u><u></u></span></span></h2><h2><span class="m_8676270477640754736event-description"><u></u> <u></u></span></h2><h2><span style="font-size:11.0pt;font-family:"Verdana",sans-serif;color:black;font-weight:normal">HOST:</span><span style="font-family:"Verdana",sans-serif;color:#1f497d">  </span><span class="m_8676270477640754736event-description"><span style="font-size:12.0pt;font-family:"Verdana",sans-serif;font-weight:normal">Andrew Cooksy</span></span><u></u><u></u></h2><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><span style="font-size:9.5pt;font-family:"Verdana",sans-serif;color:black"> </span><u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal"><span style="font-size:9.5pt;font-family:"Verdana",sans-serif;color:black">Dr. Jose E. Castillo<br>Director/Professor<br>Computational Science Research Center<br>5500 Campanile Drive<br>San Diego State University<br>San Diego, CA  92182-1245<br>(619) 59407205/3430, FAX </span><a href="tel:%28619%29%20594-2459" target="_blank"><span style="font-size:9.5pt;font-family:"Verdana",sans-serif">(619) 594-2459</span></a><u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><u></u> <u></u></p></div></div><br>______________________________<wbr>_________________<br>
