Dr. Padhu, Mathematical Scientist at George Mason University, digital footprints tells me that he is a well-known professor engaged in the Applied Mathematics field, his passion, his research interests and educational programs are all Mathematics related as well as his involvement in STEM training.
While investigating about him, most of the information was found about his learning and work rather than his personal life. This Information could be sought on Google, YouTube, and LinkedIn.
I was unable to follow him as he is not social media, thus, his digital footprint is strictly professional.
The person has several web files about him on Science and engineering as well as news articles telling about his innovations and initiatives in Mathematics and STEM Education.
Research shows that he has research interest in design and systems thinking, I found that rather interesting as that is one of our topics covered.
