Teaching Experiences as Graduate Teaching Assistant
Honors Chemistry II-Physical Chemistry (CEM 182H)
Institute: Michigan State University
Semester: Spring, 2023
Role: Teaching Assistant
Description: This course gives an introduction to Physical Chemistry with special reference to gases, solids, liquids, and phase transitions; solutios; thermodynamic processes and thermochemistry; spontaneous Processes and the second law of thermodynamics; general chemical equilibrium; acid-base equilibrium; electrochemistry; chemical Kinetics. This coruse helps students' to develop their understand on how the microscopic behavior of atoms and molecules determines the behavior of macroscopic chemical systems. As a teaching assistant I, delivered lectures (recitations), worked with faculty to ensure active learning environments for active participation during class, proctored and graded exams.
Analytical Chemistry Lab (CEM 435)
Institute: Michigan State University
Semester: Spring-2021 and Spring-2022
Role: Teaching Assistant
Description: This lab helps students' to gain experience with the following analytical instruments, GCMS, ICP-OES, Stripping Voltammetry, HPLC, Atomic Absorption to make them independent user. Then, they need to run two open ended projects to gain real world problem solving skills. As a teaching assistant, I supervised four groups (each consists of two students) of students in their undergrad projects in writing proposal, designing experiments, sample preparation, experimentation, and data analysis. Graded lab report to evaluate their working knowledge of instrument and ability to interpret data.
Molecular Spectroscopy Lab (CEM 495)
Institute: Michigan State University
Semester: Fall-2020
Role: Teaching Assistant
Description: This lab helps students' to explores forms of molecular spectroscopy in order to probe specific aspects of molecular structure and properties. As a teaching assistant, I taught some of the advanced Spectroscopic techniques like, UV-Visible spectrophotometry, Fluorescence Spectroscop, Raman & Infrared Spectroscopy, Rotational-Vibrational Infrared Spectroscopy, RoVibronic Spectroscopy by in hand experience to make them independent user. Graded and reviewed lab reports from the assigned lab experiments to evaluate their working knowledge of instrument and ability to interpret data. Performed spectroscopic analysis for unknown identification using a variety of instrumentation.
Quantitative Analysis Lab (CEM 262)
Institute: Michigan State University
Semester: Fall-2019, Summer-2021, Fall-2021
Role: Teaching Assistant
Description: This lab helps students' to gain mastery of different quantitative methods in analytical chemistry such as aqueous solution equilibira and statistics related to quantitative chemical analysis, titrimetric, gravimetic, and spectrophotometic measurements. As a teaching assistant, I facilitated two lab sections while the students performed different quantitation techniques. I guide students through experimetns, data analysis, and interpretation of results.
Instrumental Methods and Applications Lab (CEM 333)
Institute: Michigan State University
Semester: Spring-2020
Role: Teaching Assistant
Description: This lab helps students' to gain hands in experiences with the following analytical instruments, GC, HPLC, ICP-OES, Spec Basics, Atomic Absorption, FTIR, Mass Spec, Fluorescence Spectroscopy, Potentiometry, Voltammetry to make them independent user. As a teaching assistant, I supervised three sections of students in clarifying course material, answer questions, and provide guidance on methodologies, techniques, and software tools used in quantitative analysis. I guided them through experiments, data analysis, and interpretation of results.
General Chemistry Lab (CEM 162) Fall 2018 – Summer 2019
o Supervised three lab sections for each semester ensuring students can achieve basic gen-chem lab skills.
o Maintained an advanced understanding of all course material in order to accurately assist students.
o Checked setups, coached students through proper techniques in lab setting.
o Guided them in writing pre-lab plans to ensure lab safety.
o Graded and reviewed lab reports from the assigned lab sections
o Ensured that students followed all safety guidelines in labs.
o Maintained the organization of the lab and the use of lab equipment to ensure a safe lab environment.
Undergrad – Project Supervision.
Mercury (Hg) in Swordfish
Helped students to design experiments so that they can use ICP-OES to quantitate Mercury (Hg) and Lead (Pb) in sword fish. The main challenge was to overcome memory effects using L-cystine.
Metals in Vegetables/Beer
Helped students to develop a rapid method for screening the minerals present in different available vegetables/Beer using ICP-OES. Then, developed a fully quantitative method to assess the concentration of several important minerals.
Steel Powders.
Developed a rapid method for screening the minerals in steel samples using ICP-OES and then developed a fully quantitative method to assess the concentration of at least five important metals. Compared results with those provided by the manufacturer.
Bisphenol A
Used solid phase extraction and GCMS analysis in order to determine the BPA concentration in water stored in an old polycarbonate bottle.
Vitamins dissolved in Water
Developed an electrochemical assay to examine redox efficacy of nutritional supplements, focusing on water-soluble ingredients. Electrochemically identified and assessed effective electrochemical capacity of few major ingredients. Compared effective capacity to stated chemical composition, if known.
