Life Sciences 1a: An Integrated Introduction to the Life Sciences: Chemistry, Molecular Biology, and Cell Biology

Course description:

Life Sciences 1a is a fall-semester survey course that integrates general chemistry, organic chemistry, cell biology, and molecular biology at the introductory level. The course is large (typically about 300 students), with the majority of students being freshmen. The focus is on the fundamental features of living systems, with topics including intermolecular interactions, thermodynamics, acidity, (first-order) kinetics, the central dogma, cell signaling, enzyme catalysis, and transport across membranes. These concepts are then applied to consider drug design and discovery.

TF POSITION FOR FALL SEMESTER 2026: Neuro 80 (MCB 80) – NEUROBIOLOGY OF BEHAVIOR

Course Description

Neuro/MCB 80 aims to provide an in-depth introduction into the fundamentals of the brain and neuroscience. The teaching staff aims to provide a biologically inspired conceptual framework for thinking about how the brain works. The course begins by taking a close look at the nuts and bolts of neurons and signaling and then moves on to explore a few networks including sensory systems and motor systems before finishing with neurodevelopment, and “higher” cognitive topics.

We will be largely keeping the structure of the course and applying what we have learned the past several years. This year the course will be a hybrid or partially “flipped” format. Students will be responsible to watch two asynchronous lectures (or lecture equivalents) each week online. Then throughout the semester, Tuesdays and Thursday in-person lectures will feature demonstrations, guest lectures, workshops, and activities that apply the concepts discussed in the video lectures. The workshop and an opportunity for the students to ask questions to the course leaders and work through some questions. The weekly discussion sections will be lead by you the TF, where students will discuss the material, work in small groups, practice problems, and try small neuroscience labs and demos.

There are no pre-requisites for the class and it is the foundational course for students who plan to concentrate in Neuroscience.

Expectations

Watch/review video lectures and understand the material
Prepare and lead a weekly 75 min discussion section (in person) on either Thursdays or Fridays for ~16 students
Assist with grading the weekly problem sets
Prepare for and attend weekly staff meetings: Tuesdays, 9-10:15 am.
Hold weekly or biweekly office hours
Answer emails, help monitor the online chat boards/answer student questions
Help prepare exam questions, monitor/check Canvas
Help with the Neuroscience Activity Fair: Tuesday, September 4th
Attend ~5 of the T/Th lectures (10:30-11:14 Science Center) to help with questions, attendance, etc.
Proctor Exams – Midterm 1: 10/1 10:30-11:45, Midterm 2: 11/5 10:30-11:45, or Final TBA
Class runs 9/2 – 12/4 (There will be section the last week of class) Final will be held during exam period: 12/10-12/19

Total commitment ~10-15 hrs/week

Training

We will hold an all day training session/course orientation in August, featuring: teaching
scientific course material, grading, leading group work and a micro-section practice. Will likely
