Kathy Lin


Director of Admissions

 

Kathy Lin is Proof School's Director of Admissions, and leads the school’s studio program.

Kathy is a grown-up math kid with a background in math, education, and outreach.

She’s a jack-of-all-trades maker who dabbles in paper crafts, sewing, electronics, and more—whatever it takes to turn ideas into reality.

Prior to joining Proof School, Kathy spent several years at MIT developing open online education initiatives. Most recently, she spearheaded the development of the MIT OCW Educator initiative, for which she developed novel ways of sharing extensive curricular materials, describing context, and capturing instructors’ insights for noteworthy MIT courses.

Kathy has published papers in both mathematics and mathematics education, and she is currently completing her Ed.D. in mathematics education at Rutgers. Her dissertation focuses on the mathematical development of exceptionally accomplished American mathematics students. Prior to her doctoral studies, Kathy taught high school math while earning her M.A.T. and teaching license.

Kathy’s work in math education is informed by her own experiences as a math kid, most notably her summers as a student and counselor at the Ross Mathematics Program. As a mother, she has become well-versed in feeding the curiosity of young children. As the wife of a mathematician, she often chats about current research at the dinner table.

Zachary Sifuentes


Dean of Humanities + Lead Humanities

Teacher

 

Zachary Sifuentes helps students and faculty think creatively and analytically in the classroom.

He leads Proof School’s humanities program.

Zachary is an artist and writer who has over a decade of experience teaching writing and studio arts, more than half of which at Harvard and Stanford.

Zachary’s expertise in writing across the curriculum was culled in part by leading Harvard's online writing resources, HarvardWrites and the Journal of the Harvard College Writing Program. He served for a number of years as a head preceptor and faculty associate at Harvard, where he served on a multi-disciplinary team to develop courses for the college's revamped Program in General Education.

His focus on writing and mentoring helped numerous students apply for and receive the most acclaimed fellowships for college graduates: the Rhodes, Marshall, and Fulbright. He won Harvard’s Marquand Award for advising, and for three consecutive years, his students won one of Harvard’s top writing awards for freshmen. At Stanford, his students leveraged their research projects to gain valuable internships in fields like sustainability, publishing, and data analytics. 

Zachary has a particular affinity for social-emotional learning, discovered in part by the six years he served as a “dorm parent” in Adams House, an undergraduate dormitory at Harvard. His artwork has been collected by both private individuals and public institutions, and for a number of years he made artwork for Emory University's renowned poetry reading series.

Prior to teaching, Zachary was an AmeriCorps*VISTA volunteer in rural Puerto Rico, where he raised $1.5 million to open a health clinic for children with disabilities.

Sam Vandervelde


Head of School + Dean of Mathematical Sciences

 

Sam Vandervelde sets the stage for students and faculty to engage actively and creatively with mathematics.

Sam received his Ph.D. in mathematics from the University of Chicago in 2004, following a five-year stint teaching and coaching sports at the Roxbury Latin School, a private boys school in the Boston area.

Sam also taught at Phillips Academy Andover and at Wellesley College before joining the faculty at St. Lawrence University in 2007. Prior to Proof School’s opening, Sam served as a tenured professor and math department chair at St. Lawrence. Sam’s mathematical interests encompass number theory, graph theory, combinatorics, and Euclidean geometry.

While at St. Lawrence Sam wrote a textbook, Bridge to Higher Mathematics, and organized the Festival of Science, an annual college-wide event showcasing student research. He also received the Alder Award, a national teaching award given by the Mathematical Association of America. He has conducted numerous research projects with his college students and also ran a math club at the local middle school.

Prior to arriving at St. Lawrence, Dr. Vandervelde participated in a number of math circles in the San Francisco Bay Area, forming and directing the Stanford Math Circle for two years. He has been involved with MathPath, a month-long residential summer program for middle schoolers, for 10 years and is currently a member of their board. He authors and oversees all aspects of the Mandelbrot Competition, a national high school math contest.

In addition, Sam regularly contributes problems to and helps write the USA Math Olympiad. As a high school student Sam won ARML and was also a member of the United States IMO team his senior year. He loves teaching math kids.
