Dr. Vishwajit S. Chowdhury, P.I.

私は1998年にバングラデシュのダッカにある日本大使館の推薦により広島大学に留学し、組織生理学の博士号取得につながる修士課程を修了しました。2004年に博士号を取得した際、ストレス生理学の研究業績が認められ、広島大学学長から学長特別賞を受賞しました。2004年から2008年まで、広島大学と早稲田大学で、イモリ、ウシガエル、ウズラ、ニワトリ、サル、ヒトなどさまざまな生物種を対象に、博士研究員として新規RFアミンデ神経ペプチドとその相同体について研究しました。2008年には法政大学で実験生物学の講師を務め、2009年には東京医科歯科大学生物学部の非常勤教授(准教授)として問題解決型学習を教えました。2010年からは九州大学で働いています。
九州大学に着任後、私は養鶏業界にとって大きな脅威である鶏の暑熱ストレスについて研究を始めました。私たちは暑熱ストレスのいくつかの生理学的および代謝的マーカーを明らかにし、体温調節の役割を果たすL-シトルリン、L-ロイシン、タウリンなどのアミノ酸を発見しました。アミノ酸の他に、私はストレスと免疫機能を制御する神経ペプチド、すなわち神経ペプチドYとそのファミリーメンバーにも焦点を当てています。
私の主な所属は、九州大学基幹教育院です。また、共創学部、資源生物科学部門、生物資源環境科学府にも所属しています。九州大学アジアオセアニア研究機構自然クラスターの持続可能な食肉生産モジュールのメンバーでもあります。
I came to Japan in 1998 at Hiroshima University by the recommendation of the Japan Embassy, Dhaka, Bangladesh, to study Masters leading to PhD on Histophysiology. The President’s Distinction Award was given to me during my Ph.D. graduation in 2004 from the President of Hiroshima University for my research achievements in Stress Physiology. I had studied on novel RFaminde neuropeptides and their homologs at Hiroshima University and Waseda University from 2004 to 2008 as a Post-doc researcher in difference species, namely, newt, bullfrog, quail, chickens, monkey and humans. I was a Lecturer of Experimental Biology at Hosei University in 2008 and worked as an adjunct Professor (Associate) in the Department of Biology at Tokyo Medical and Dental University in 2009 to teach Problem-Based Learning. Since 2010, I have been working at Kyushu University.
After joining Kyushu University, I have started to study on heat stress in chickens, which is a major threat in poultry industry. We have revealed some physiological and metabolic markers of heat stress and discovered some amino acids, namely, L-citrulline, L-leucine and taurine, which have thermoregulatory role. Besides, amino acids, I am also focusing on neuropeptides, namely neuropeptide Y and its family peptides in controlling stress and immune functions.
My main affiliation is with the Faculty of Arts and Science, Kyushu university. I am also affiliated with the School of Interdisciplinary Science and Innovation and Graduate School of Bioresource and Bioenvironmental Science. I am a member of the Sustainable Meat Production Module of the Natural Cluster, Kyushu University Institute for Asian and Oceanian Studies.
