During a recent job interview, I was asked how I tackle ambiguous problems. It was the perfect opportunity to showcase not just my technical experience, but also a powerful tool in my leadership arsenal: meditation.My practice, learned from the Art of Living Foundation's SKY program, has been a game-changer. It helps me stay centered and manage anxiety, allowing me to approach challenges with a clear head and unwavering faith in my abilities. The positive impact extends beyond me – witnessing the power of mindfulness and meditation during my 100s of hours volunteering with Art of Living ignited a passion to share this knowledge with others.That's why I took the plunge and underwent their SKY Leadership Training program. Now, I'm certified to lead 1-hour meditation and wellness workshops, guiding participants through mindfulness exercises, breathing techniques, and group meditations. I am glad to share these practices with others and do my bit to tackle the mental health pandemic. I invite you to my next session on the 25th of April 2024 from 3-4 PM ET in LCC, Purdue University. P.S.: I am looking for an exciting full-time opportunity where I can leverage my expertise in aerospace engineering, software development, and program management to drive innovation and make a meaningful impact.

📢 Excited to share my recent journey into the realm of arithmetic operations on large integers in C++!Have you ever wondered how arithmetic operations on integers with 100,000s of digits can be performed in a low-level language like C++ without relying on external libraries? Last month, I encountered this challenge head-on, sparking my curiosity to dive deep into the intricacies of sophisticated algorithms that tackle this problem.It's a fascinating two-pronged challenge: efficiently storing massive numbers and implementing advanced algorithms to manipulate them. During my exploration, I was astonished by the elegance of algorithms like Karatsuba and Schönhage-Strassen, which ingeniously navigate the complexities of large integers, significantly reducing the time complexity of multiplication, exponentiation, and division.The end result? A meticulously crafted and well-tested toolbox that allows users to perform arithmetic operations (+, -, *, /, %, ^) on large positive integers, ranging from thousands to tens of thousands of digits. On top of that, I programmed the Fast Fourier Transform (FFT) in 2 different ways for the Schönhage-Strassen algorithm, adding even more versatility to my toolkit.And the best part? My core implementations don't rely on non-standard libraries like FFTW, GMP, and Boost, ensuring their accessibility and portability across different environments. But the journey doesn't stop here! I'm eager to expand this toolbox to include operations on floating-point numbers.For more details, check out my GitHub repository: https://lnkd.in/gd46pzirand for my other projects: https://lnkd.in/gpqYVKt5P.S.: I am looking for an exciting full-time opportunity where I can leverage my expertise in aerospace engineering, software development, and program management to drive innovation and make a meaningful impact.#Cpp #SoftwareDevelopment #AerospaceEngineering #opentowork

James Webb Space Telescope (JWST) for most people is special because it has given unprecedented insight into our past, and images that make for killer desktop backgrounds!I find it particularly interesting because of the orbit it is in. The telescope‘s orbit is near the Sun-Earth L2 point and it is modeled as a Quasi-Periodic Orbit (QPO) in the Circular Restricted 3 Body Problem (CR3BP) model.QPOs are the centerpiece of the research that I have been pursuing for the past 1.5 years as part of the Multibody Dynamics Research Group. JWST’s orbit highlights the significance and feasibility of the work that I am doing!QPOs are mathematically complex to understand and notoriously difficult to numerically compute. In addition, it is not an easy feat to communicate their behavior, challenges, and benefits.Nonetheless, their numerous benefits outweigh the challenges. They can specifically be leveraged for formation flying and solar sail trajectory design, and provide increased solution space for transfer design in a multibody system.Through this journey, I have learned a great deal about dynamics modeling, numerical methods, trajectory optimization, 3D visualization, solving constrained dynamical problems, and software engineering.This experience and my improved technical communications skills have made me more adept at solving hard engineering problems. I can't wait to continue to make progress with my research and use my knowledge to contribute to the technological developments in robotics and space travel to sustainably improve our lives on Earth.P.S: The below animation is a summation of the work and learnings of the past 1.5 years!

I vividly remember participating in weekly Astronomy and Robotics club sessions in my middle school. The two clubs exposed me to how I can apply the math and science concepts that I was learning in school to realize the wonders of our Universe and to make “cool” robots. It was then that I discovered my passion for Aerospace Engineering and Robotics, which led me to become an Aerospace Engineer and now to pursue Astrodynamics in graduate school.This past summer, I got to pay forward the efforts of those club instructors through a unique opportunity with the Minority Engineering Program(MEP) at Purdue University where I worked as a Summer Fellow. I designed courses around robotics and co-instructed them to 6-8th grade and 12th-grade students from around the U.S. using the NXT and Hummingbird kit.I am grateful to Juan Camilo Mesa Agudelo, Brad Thompson, Steve Florence, and Nadia Numa, who extensively helped me to make it possible.My 2 biggest takeaways from creating and co-instructing the course:1. Keep students engaged by knowing how to challenge the students with more experience and providing extra support to students who are less familiar with the concepts.2. Adapt coursework on the fly as not all project components will go according to the plan, so it is better to plan to have time to tackle any unexpected delays and challenges.Besides teaching robotics to the students, I was able to share with them my passion for aerospace engineering, robotics, intricate projects that I got to work on in my undergrad, and my current research in astrodynamics centered around quasi-periodic orbits.I am excited by the prospect that some of the students that I interacted with will start at Purdue next year and some of them are considering pursuing a career in aerospace engineering and robotics after learning about the projects that I worked on and my research!This semester, I am getting another unique opportunity to learn from Dr. Tim Peoples and to assist him with his ENTR 500 course focused on technology commercialization.I can't wait to see what the last stretch of my master's journey holds! #robotics #aerospaceengineering P.S.: I will be forever grateful to Darshini Render and Prof. John Howarter for mentoring me during my time at Engineering Undergraduate Research Office, which prepared me for my role with MEP and to TA ENTR 500.

I did it!!!!! I graduated with B.S. Aeronautical & Astronautical Engineering and minor in Astronomy with the highest distinction from Purdue University in 3.5 years!My undergraduate journey at Purdue was filled with much more challenges than I had anticipated in the beginning, especially with everything that went down last year. Last year was especially tough for me because I lost my grandfather and an internship opportunity with OneWeb. Nonetheless, I am forever grateful for the invaluable learning experience and the chance to be part of many diverse projects.I am particularly thankful to Dhruva Space for their guidance and irreplaceable experience that I gained through two summer internships, which I spent designing multiple satellite constellations and coding an ADCS simulator.My key takeaway from my undergraduate journey is to embrace uncertainty, as often things do not go as planned. It is at that time a person needs to stay patient and continue to persevere as opportunities have a unique way of showing up.I am stoked to share that I will be beginning M.S.AAE focused on Astrodynamics and Space Application at Purdue University under Prof. Kathleen Howell as part of her Multi-Body Dynamics Research Group.Boiler Up!
