![“I wasn't discouraged by some of the obstacles we faced. I learned a lot from the leadership. I found that different people need different ways of receiving feedback — you can't [just] tell them to do something and expect the best. [Some] people needed more incentive. A large part of my role was to figure out what worked for everyone and to figure out how to lead all these separate individuals as a team,” Suhana Bhandare (’26) said.](https://harkeraquila.com/wp-content/uploads/2026/06/SuhanaBhandare_JasmineHansra-1-1200x798.jpg)

That's what I've always been able to do with tennis, Link Crew and getting that internship [with Kushy Baby]. It’s important pushing through that — getting around that brick wall, climbing over it or clawing through it,” Yash Sachdeva (’26) said.](https://harkeraquila.com/wp-content/uploads/2026/05/YashSachdeva_RamBatchu-copy-1200x1002.jpg)
![“[Building nerf blasters] became this outlet of creativity for me that hasn't been matched by anything else. The process [of] making a build complete to your desire is such a painstakingly difficult process, but I've had to learn from [the skills needed from] soldering to proper painting. There's so many different options for everything, if you think about it, it exists. The best part is [that] if it doesn't exist, you can build it yourself," Ishaan Parate said.](https://harkeraquila.com/wp-content/uploads/2022/08/DSC_8149-900x604.jpg)

It helped me overcome my fear of public speaking, and it's played such a major role in who I've become today.

Cybersecurity engineer Dr. Frank Wang (’08) delivered a lecture on cryptography and security in a joint Math Club and Programming Club meeting on Friday.
Dr. Wang discussed a technique in cryptography, the science of encoding information for secure communication, called secret sharing. In secret sharing, a dealer splits sensitive information into multiple pieces to distribute to different parties so that no single person can access the secret.
“A good application is that when you’re on the internet and using [Secure Sockets Layer security], Chrome has hard-coded keys for certificates it trusts,” Dr. Wang said. “A lot of times there’s one trusted party generating the key or holding the key, and that might be too much trust for one person. Maybe you’re worried that if someone hacks into one machine they can take all of it.”
Dr. Wang explained two approaches to secret sharing. In Shamir’s Secret Sharing, sensitive information is embedded in a polynomial function, which can be recovered only if a certain number of points on the polynomial are known. Function Secret Sharing (FSS) is a newer technique that distributes multiple pieces of a function that can be summed to obtain the original secret.
“I know some random stuff about cryptography, but I’ve never heard of secret sharing,” attendee Andrew Shi (10) said. “As someone who studies math, it’s just fun and inspiring to learn about interesting ideas, even if you’re not going to work in the field of cryptography or theoretical computer science. It still stimulates your mind.”
Dr. Wang concluded the session by answering questions related to his career, like the process of obtaining his cryptography PhD and his current role at artificial intelligence startup Surge AI. The meeting was arranged by math teacher Bradley Stoll and co-hosted in a collaboration between Math Club and Programming Club.
“The goals of this meeting are to attract a wider audience, so we had members from both math and CS clubs attending this lecture,” Math Club officer Elaine Xu (11) said. “People usually feel like math is a very abstract topic that doesn’t have as practical of an application. This helps connect […] higher level math to security and how it can actually make our browsers and our computer systems safer.”
