LEWISTON — Bates College will present lecturers offering insight into mathematics and medical technology during the week of Feb. 24.

Leila Schneps, a mathematician specializing in number theory (and moonlighting as a murder-mystery author), delivers this year’s Sampson Lecture at 7:30 p.m. Wednesday, Feb. 26, in the Benjamin E. Mays Center, 95 Russell St.

Sponsored by the mathematics department, the annual Sampson Lecture is open to the public at no cost.

Robert S. Langer, one of the best-known figures in engineering, offers two lectures on Friday, Feb. 28, under the auspices of the George S. Hammond ’43 D.Sc. ’73 Eminent Scientist Lectures, sponsored by the chemistry department.

He gives the technical lecture “Novel Drug Delivery Systems and the Application of High Throughput Approaches to Drug Delivery and Stem Cell Technologies” at 4:10 p.m. in Room 119, Dana Chemistry Hall, 5 Andrews Road (Alumni Walk).

At 7:30 p.m., Langer delivers a talk for the lay audience titled “Biomaterials for the 21st Century and How They Will Change Our Lives” in Olin Concert Hall, 75 Russell St. Admission to both lectures is free, but tickets are required for the evening event, available at bit.ly/oacbates.

For more information about all three events, call 207-786-8371.

An American mathematician, Schneps is a researcher at the French National Scientific Research Center, specializing in number theory and algebraic geometry.

She has a long-standing interest in the mathematical aspects of crime detection, focusing on ways in which math —  through both the correctness of its application and the manner of its presentation by expert witnesses — can influence trial outcomes and lead judge and jury toward the truth, or away from it.

Schneps and her daughter, Coralie Colmez, co-wrote “Math on Trial: How Numbers Get Used and Abused in the Courtroom.” They are members of the Bayes in Law Research Consortium, an international team devoted to improving the use of probability and statistics in criminal trials.

Writing as Catherine Shaw, Schneps has also published several murder mystery novels, set in the legendary mathematics department of Cambridge University in the 19th century and built around a real math problem that tested the greatest minds of the time.

The annual Sampson Lecture honors the late Professor Richard W. Sampson, who taught math at Bates for 38 years.

Langer is the David H. Koch Institute Professor at the Massachusetts Institute of Technology (an Institute Professorship being the highest honor that can be awarded to an MIT faculty member). Langer received an honorary degree from Bates in 2011.

Langer’s work has led to products that treat cancer, diabetes, heart disease and schizophrenia, among other diseases. MIT’s Langer Laboratory is on the front lines of turning research discoveries into drugs and drug delivery systems.

Langer has written more than 1,230 articles and has some 512 patents issued worldwide. His patents have been licensed or sublicensed to more than 250 pharmaceutical, chemical, biotechnology and medical device companies. He has received more than 220 major awards, including the U.S. National Medal of Science, the U.S. National Medal of Technology and Innovation, and the Charles Stark Draper Prize, considered the equivalent of the Nobel Prize for engineers.

The Hammond Eminent Scientist Lecture Fund is given in honor of George S. Hammond by his associates and students from Iowa State College under the guidance of Jay K. Kochi. The fund supports lectures by scientists specifically chosen by students and faculty in the Bates chemistry department. Hammond, who died in 2005, is widely credited with creating the discipline of organic photochemistry.
