BIOLOGY DEPARTMENT
This past year saw major physical changes in the
biology facility. The Unified Science Center is fast becoming a
reality and the biology building has been vacated for renovation over
the course of the next year to fully integrate the old with the
new.
The Biology Department continues its
tradition of strong course offerings and research opportunities. This
past year saw a record number of honors theses with 28 students, 12
of whom received Highest Honors for outstanding performance on the
senior thesis. The department has a total of 125 junior and senior
majors for 1999-2000 academic year.
Each year at graduation, the Biology
Department awards prizes to five outstanding majors. We are pleased
to announce that this year’s recipients were Kate Dreher ‘99,
who received the Conant-Harrington Prize for exemplary performance in
the biology major; Jennifer Pogoriler ‘99 and Kevin Bolduc ‘99,
who were awarded respectively, the First and Second Benedict Prize
for excellence in biology; Jennifer DeNiro ‘99, who received
the Dwight Prize as the ranking student in botany; and Sylvia Englund
‘99, who was awarded the Grant Prize for the student
demonstrating excellence in a broad range of areas in biology. Twelve
students were nominated for induction into Sigma Xi, the national
research society.
Karen Theiling, who for the past several
years did an excellent job as part-time instructor in the
introductory and physiology laboratories, has resigned her position
to embark upon a new career in the field of psychological counseling
and has accepted a position here at Williams. While we will miss her
many contributions to the department, we wish her well in her new
endeavor.
Gretchen Meyer has accepted a
research/forest management position at the University of Wisconsin
and will be leaving at the end of June. We wish her great success in
this new role.

Senior Honors Poster Presentation
This past year, Prof. Altschuler taught BIOL
132, Human Biology and Social Issues in the fall and BIOL 306,
Advanced Molecular Genetics in the spring. Work continues in
Professor Altschuler’s lab on projects directed toward
elucidating the genome organization of the ciliated protozoan,
Tetrahymena thermophila. Inna Hughes ‘99 and Anh Nguyen ‘99
worked on developing vectors and methods to be used in a “chromosome
fragmentation” protocol for determining the position of cloned
DNA sequences within Tetrahymena somatic chromosomes. Kian
Peng Koh ‘99 adapted a 2-D gel electrophoretic procedure for
mapping replication origins on chromosomes. Leah Doret ‘99
developed a PCR-based method for obtaining DNA sequences located near
the ends of chromosomes.
During the 98-99 academic year Prof. Henry
Art taught BIOL 220, Field Botany and Plant Natural History
and ENVI 302, Environmental Planning and Design Workshop.
He also took part in the Hoosic River Watershed Association’s
Scientists and Artists in the Classroom Project. Prof. Art was
awarded a Mellon Grant for technology in the classroom to further
develop electronic media for BIOL 220, and is developing a web page
for the Hopkins Memorial Forest with Harin Tantongsirisak ‘00.
He is currently Director of the Center for Environmental Studies at
Williams College and serves on the Scientific Advisory Committee,
Edmund Niles Huyck Preserve and Biological Research Station,
Rensselaerville, New York. Prof. Art also serves on the Board of
Advisors for the Ecosystem Science Semester Program at the Ecosystem
Center, Marine Biological Laboratory, Woods Hole, MA. He was awarded
the 1998 Educator Award by the New England Wild Flower Society and
was a contributor to the book Wildflower Gardens, pp 6-12 “A
Gardener’s Ecology,” Brooklyn Botanic Gardens, Brooklyn,
NY.
Associate Professor Dan Lynch continued as
Chair of the Department, and taught BIOL 412, Biochemical
Regulatory Mechanisms and BIOL 322, Biochemistry II.
Professor Lynch continued his research on plant sphingolipid
biochemistry, funded by grants from the NSF and the NIH, and
supervised the Honors projects of Julie Cantatore ‘99 and
Yuneng Li ‘99. He published a paper, with Pam Bromley ‘98,
titled “The Structure and Synthesis of
Inositolphosphorylceramides in Plants.” Professor Lynch served
as a reviewer for the NSF and for a number of journals.
With funding from Williams’ Mellon
Project, Assistant Professor Wendy Raymond and Huei Wong ‘99
developed a multi-faceted website for BIOL 202,
Genetics,
which served 95 students in that fall course. Check it out at
http://hector.williams.edu/biology/courses/biol202/.
During Winter Study, eight sophomores and two first-year students got
hands-on, feet-first experience with laboratory research in
cell-cycle regulation in Raymond’s course
Research in
Molecular Genetics. Six of these students subsequently garnered
paid summer research positions in laboratories across the country,
fantastic accomplishments for students at such early stages of their
scientific education. Raymond also supervised Samantha Grant’s
independent Winter Study project, “Scanning Electron Microscopy
Photography,” which was completed under the direction of our EM
technician Nancy Piatczyc (
http://wso.williams.edu/~sgrant/SEM.htm).
In the spring, Professor Raymond taught BIOL
313, Immunology, with 45 students in this lecture and lab
course.
Raymond’s research program continued
to probe the molecular relationships between two particular genes
important for the resolution of mitosis. During the summer of 1998,
Sylvia Englund ‘99, Michael Hurwitz ‘00, Amy Patterson ‘99,
and Melissa Schmidt ‘99 kept the lab hopping. Raymond gave a
talk summarizing the work of previous thesis students at the Yeast
Genetics and Molecular BIOL Meeting, an international conference with
1000 participants. During the academic year, Sylvia Englund ‘99
and Amy Patterson ‘99 completed honors theses under Raymond’s
direction, and Melissa Schmidt ‘99 worked as an independent
study student.
This past year Nancy Roseman team-taught the
introductory biology course (BIOL 101) with Professor Laskowski. In
the spring semester she taught BIOL 314,
Virology, a course
that the department offered for the first time in three years.
Professor Roseman had three honors students who made substantial
progress working on projects funded by her NSF grant. Kevin Bolduc ‘99
and Ayesha Johnson ‘99
used temperature
sensitive mutants of a
vaccinia virus protein kinase to
determine whether the
vaccinia enzyme dUTPase is a substrate
for these kinases. Jennifer Pogoriler ‘99 engineered a
vaccinia dUTPase mutant by using a dominant selectable marker
combined with a color screen gene. This summer, Prof. Roseman and
Prof. Lovett of Chemistry will again share a Merck Fellow, Maywa
Montenegro, who will be doing kinetic analysis of dUTPase.
This past year, Professor Robert Savage
taught BIOL 301, Developmental Biology, and a senior seminar
course entitled Topics in Cell, Molecular and Developmental
Biology. He and Denise Buell (Religion Department) introduced a
new course during the Winter Study term entitled In the Beginning?
Scientific and Religious Speculation on Human Origins, in
which students examined a range of theories on the origins and
development of life from Aristotle to Darwin. Prof. Savage was an
honors thesis advisor for Janet Iwasa ‘99, Daniel Suver ‘99
and Arianna Sainz ‘99. Janet and Dan presented their thesis
work at the annual Northeast Regional Development Biology meeting
held at the Marine Biological Laboratory. Arianna initiated a study
examining segmental pattern formation in a basal polychaete
Capitella.
Prof. Savage was awarded a three year grant
from the National Institutes of Health to support his continuing
research on pattern formation in annelids. He also was an invited
instructor for the course Neurobiology and Development of the
Leech, offered at the Marine Biological Laboratory in Woods Hole,
MA. The course was designed for graduate students, postdoctoral
students and independent investigators interested in applying diverse
experimental approaches to the study of the nervous system and the
development of the leech. Prof. Savage served as a reviewer for the
National Science Foundation and for two textbooks published by
McGraw-Hill and Blackwell Science.
Assistant professor Steve Swoap taught BIOL
309, Mammalian Molecular Physiology and laboratories that
accompanied the introductory biology course (BIOL 101) in the fall
and BIOL 205, Physiology in the spring. Prof. Swoap also
taught a new Winter Study class, Science in Sports, with
Daniel Aalberts of the Physics Department. He was the honors thesis
advisor for John Haney ‘99 and Deborah Van Allen ‘99.
Haney was a co-author on a poster presentation at the Experimental
Biology meetings in Washington, D.C. in April. Swoap also had three
independent study students in his laboratory - Nilesh Kansagra ‘99,
Margaret Genovisi ‘99, and Leigh Olmstead ‘99. Swoap
served as a reviewer for the Journal of Applied Physiology. In
addition, he coordinated the outreach program funded by the Howard
Hughes Medical Research Institute, with Vanessa Alvarez ‘00
working in his laboratory three weeks. Swoap gave a guided tour
through the heart to three classes of 6th graders from the local
elementary school. This coming academic year Prof. Swoap will be
offering a new non-majors course, Biology of Exercise and
Nutrition.
Associate Professor Heather Williams taught
the Animal Behavior course in the fall of 1998. This course
was reconfigured as a Critical Reasoning and Analytical Skills
course, and as such was featured in the annual President’s
Report. In the spring she participated in teaching the second
semester of the introductory biology sequence, and with Gretchen
Meyer, co-taught a Winter Study course entitled The Naturalist’s
Winter.
Denise Connor and Brett Linck completed
honors theses in Williams’ lab, working on, respectively,
mechanisms for adult plasticity in zebra finch song and central and
peripheral responses to injuries of the nerves supplying the vocal
organ. Examples of the songs analyzed as part of this work can be
viewed at the Zebra Finch Song Archive, a resource that is being used
by other researchers around the country. (
http://wso.williams.edu/~hwilliam/ZFsongs/)
With Neil Mehta (‘95), Williams
published “Changes in Adult Zebra Finch Song Require a
Forebrain Nucleus That Is Not Necessary for Song Production” in
the Journal of Neurobiology.
Prof. Williams presented her work at the
Bird Song Workshop at Vassar College, and at the Rockefeller
University Field Research Center. She served as a reviewer for
several professional journals and for the NSF, and continued as a
member of a review panel for the National Institutes of Health.
Prof. Zottoli was on leave this academic
year. He continued to administer the 1996 Howard Hughes Medical
Institute grant to Williams College. The research interests of his
laboratory to focus on the neural basis of behavior and responses of
the nervous system to injury, work that is supported as part of a NIH
program project grant to MCP Hahnemann University. His laboratory was
visited by Christopher Reeve after graduation. Stephanie Min and Xiao
Tan ‘02 had the opportunity to discuss recent regeneration
research with Mr. Reeve.
While on sabbatical, Prof. Steve Zottoli
continued to direct a Williams College program at the Marine
Biological Laboratory in Woods Hole, MA during the months of July and
August. Dafina Brody ‘01, Anthony Ndirango ‘00, Biniam
Gebre ‘00, Gina Parra ‘99, and Boudhayan Sen ‘00
participated in this program. It included reading papers of various
scientists in residence at the MBL, meeting with each scientist to
discuss the papers and career path issues and then conducting a
laboratory exercise that related to the scientist’s area of
interest. In addition, students had the opportunity to attend course
lectures and evening lectures. Finally, students were able to conduct
original research on identified neurons in fish.
Bridie Newman ‘95, Heather Rieff ‘93
and Chris Winters ‘95 were co-authors on an article entitled: “Decrease
in Occurrence of Fast Startle Responses after Selective Mauthner Cell
Ablation in Goldfish (Carassius auratus) published in J.
Comp. Physiol. A. He attended the Society for Neuroscience
meeting held in Los Angeles with Biniam Gebre ‘00 and presented
a poster entitled: “Behavioral Recovery of Fast Startle
Responses after Spinal Cord Crush in Goldfish Can Occur in The
Absence of Mauthner Cells” that was co-authored with Deborah
Feiner ‘94, John Hering ‘94 and Don Faber.
