威廉姆斯學(xué)院Williams College

Charles導(dǎo)師是威廉姆斯學(xué)院化學(xué)講席終身正教授，在威廉姆斯學(xué)院設(shè)有毒理學(xué)、生物化學(xué)等課程，曾任威廉姆斯學(xué)院化學(xué)系主任、生物化學(xué)與分子生物學(xué)項(xiàng)目主任，擁有康奈爾大學(xué)生物化學(xué)博士學(xué)位。

Charles導(dǎo)師的研究結(jié)合遺傳學(xué)、蛋白質(zhì)組學(xué)和生化分析，了解SOS基因產(chǎn)物的綜合活性如何為細(xì)胞對(duì)DNA損傷的反應(yīng)提供幫助。他的研究獲得了美國國家科學(xué)基金會(huì)和美國國立衛(wèi)生研究院的大力支持，聚焦DNA損傷的SOS修復(fù)，在國際知名期刊發(fā)表論文數(shù)十篇。

Prof.Charles’s teaching experience includes program in biochemistry and molecular biology;team-taught,interdisciplinary courses on AIDS,globalism,and the renovation of the Thompson Science Buildings and addition of the Morley Science Labs that,at the time,was the largest capital project in the college’s history.He has also co-taught a science camp for local elementary school students and teachers and mentored dozens of students in your laboratory’s study of DNA repair.He served as director of the Bronfman Science Center and chair of the Science Committee for more consecutive years than one would think humanly possible.

The research in his laboratory focuses on the SOS response in the bacterium Bacillus subtilis.Using a combination of genetic,proteomic,and biochemical analyses

his group is trying to understand how the integrated activities of the SOS gene

products provide for the cell’s response to DNA damage.

項(xiàng)目背景

偵探小說女王英國作家阿加莎的偵探小說之所以極具魅力，很大程度上與她在藥房的工作經(jīng)歷和對(duì)化學(xué)物毒性的深刻了解密不可分。毒理學(xué)之父帕拉塞爾蘇斯提到：“萬物皆毒物，因?yàn)橐磺形镔|(zhì)皆具毒性。只有劑量決定一件事物不是毒物”?，F(xiàn)代毒理學(xué)是一門基于化學(xué)、生理學(xué)、生物學(xué)、藥理學(xué)、病理學(xué)理論，以流行病學(xué)和臨床學(xué)方法，研究外源因素對(duì)生物系統(tǒng)的毒性反應(yīng)和機(jī)制，對(duì)毒性進(jìn)行科學(xué)定性定量評(píng)價(jià)的科學(xué)。毒理學(xué)的事實(shí)是否果真如此？如何鑒定毒性？不同毒物是否都以同種方式產(chǎn)生毒性？毒性在人體內(nèi)如何處置與代謝？哪些生化機(jī)制可以對(duì)抗毒性？這些問題將在項(xiàng)目中逐一得到解答。
