Shreesh - Know your tutor

I am currently pursuing my PhD at the prestigious Shiv Nadar Institution of Eminence, where I am deeply involved in research and academic pursuits. Prior to this, I obtained my Master's degree in Nuclear Science, which provided me with a solid foundation in advanced scientific principles and research methodologies. My academic journey has been primarily focused on Physics and Astrophysics, areas where I have developed a strong expertise. I am actively engaged in research projects that explore fundamental questions about the universe, leveraging my skills in both theoretical and experimental physics. In addition to my research, I also have considerable teaching experience, particularly in the fields of Mathematics, Physics, and Engineering. Over the years, I have had the opportunity to guide and mentor students, helping them grasp complex concepts and develop their analytical skills. This combination of research and teaching has enriched my academic career, allowing me to contribute meaningfully to both science and education. I am passionate about pushing the boundaries of knowledge in Physics and Astrophysics, aiming to contribute to groundbreaking discoveries in these fields. My experience in teaching has also allowed me to develop effective communication and leadership skills, which I use to inspire and guide students in their academic journeys. Furthermore, I frequently collaborate with fellow researchers, both within and outside my institution, to explore interdisciplinary approaches that bridge gaps between theoretical concepts and practical applications. This dynamic environment keeps me constantly learning and growing as both a researcher and educator.

Class overview

I primarily focus on a requirement-based tutoring approach, tailoring my teaching methods to the specific needs and learning styles of each student. This means my teaching style is highly dynamic and adaptable, changing as needed to address the particulars of each student's situation. Whether the student needs a traditional lecture-based approach to grasp theoretical concepts, an activity-oriented method to encourage hands-on learning, or an example-based style to apply principles to real-world scenarios, I adjust my strategies accordingly. I also emphasize personalized assistance when tackling complex concepts and solving challenging problems, ensuring that students receive targeted support where it’s most needed. My goal is to create an engaging learning environment where students feel confident to ask questions and explore topics in-depth. I firmly believe that a solid understanding of core concepts is the foundation for mastering any subject. To this end, I prioritize conceptual clarity in my teaching, making sure students grasp the underlying principles before moving on to advanced topics. Problem-solving skills are equally essential, as they allow students to apply what they’ve learned in practical situations. By guiding students through a variety of problems, I aim to strengthen their analytical thinking and equip them with the tools to tackle new challenges independently. This dual focus on conceptual clarity and problem-solving remains central to my teaching philosophy, helping students not only succeed academically but also build a deeper, lasting understanding of the subject matter.

Mathematics concept taught by Shreesh

Student learned 15 days ago

S Sahai assisted a student from the University of California, Los Angeles, with a transshipment problem. The lesson focused on setting up the problem in Excel and using the solver function to minimize transportation costs. They defined variables, constraints, and the objective function, and also discussed why the solver naturally produces integer solutions. The learner will work on question three in a future lesson.

S Sahai guided Harshita through a practical application of business analytics, specifically tackling a transportation problem. The lesson centered on structuring the problem within Excel and employing Solver to optimize and minimize transportation costs. Together, they established definitions for inflow, outflow, balance, and constraints, and calculated total costs using SUMPRODUCT. Harshita will finalize the problem setup and solution, which S Sahai will review in their subsequent lesson.

S Sahai tutored a student from Brentwood on using Excel's solver function to determine coefficients for linear and quadratic regression models. The learner worked on minimizing the sum of squared differences to find optimal values for B0 and B1 in both linear and quadratic equations. They plan to cover the next question, which involves constraints, in their next lesson on Tuesday.
