Roger Tang
Hello! My name is Roger Tang, and I will be an 11th grader at Ladue Horton Watkins High School this fall. My favorite subject is science, and I have actively participated in several STEM competitions. I have participated in science olympiad since I was in 6th grade. Last year, I competed in the WashU Chemistry Tournament, where I placed third in Wacky Elements (Division Avogadro). In addition, I participated in the You Be the Chemist Challenge, where my team won back-to-back state championships.
This year, I was selected as a Finalist in the St. Louis Science Fair Honors Division and was nominated to present at the American Junior Academy of Sciences Symposium. In my first year in policy debate, I also qualified for the State Competition. This summer, I will be raising funds for Journey of Hope by tutoring students in Science Olympiad and the You Be the Chemist Challenge.

Hello, my name is Lucas Ruan. I will be a sophomore this fall at Clayton High School. Academically, I have qualified for AIME(American Invitational Mathematics Examination) for the past two years. I enjoy playing violin and piano, having participated in Missouri's All State Orchestra and having performed in Carnegie Hall with YPSO. I also won honorable mention at the state MMTA piano competition this past year. This summer, I am available to tutor both competitional and school math.

I have qualified for Mathcounts Nationals in 8th grade, performed well in MCTM competitions since the 4th grade, qualified for AIME twice, and was on the Missouri team for ARML. I am also part of my school's Science Olympiad team, and have gotten first multiple times at the state level and also second and fifth at the national level. I also participate in HOSA, winning first place in the General Chemistry event at the State Leadership Conference (SLC) and qualifying for the International Leadership Conference (ILC) with my second place in Epidemiology. I have also participated in the Washington University Chemistry Tournament (WUCT), placing second individually in the Bronsted Division. Outside of academics, I am an alternate timpanist in the Missouri All State Band, and participate in many groups and ensembles as a percussionist. This summer, I will do online math tutoring, including but not limited to Number Sense tricks, AMC 8, and MCTM to raise money for JOH.
Albert Shi
Hi, my name is Albert Shi, and I am going to be a freshman at Ladue High School in the coming fall. I have played chess for 8 years. My USCF chess peak rating is 1908, and I have won the K-5 State Championship in 2023 and participated in the National Rockefeller tournament representing Missouri. More recently, I placed 2nd at the 2026 K-8 State Championship. Academically, I have achieved the AMC8 Math Competition's Superior Honor Roll in 2026 and the AMC8 Honor Roll in 2025, skipped 2 grades of math, and I have participated in the You Be The Solution Challenge, where our team won the state championship in 2026, while also placing 6th nationally. Furthermore, I auditioned for the 2026 All Suburban Honor Band, placing 3rd chair this past year in clarinet, and achieved the highest rating in the Solo-Ensemble Music Festival. This summer, I will tutor chess for both beginners who are new to the game and intermediate players with some sense of familiarity.

Hello, I’m Kevin Diao, and I will be a senior at Ladue Horton Watkins High School this fall. I have a strong passion for science and engineering. In particular, I like designing and creating with 3D printing; I even designed and taught a 3D printing class at a modern Chinese school. As a member of the robotics team, I am responsible for 3D design, and I’ve created designs for
educational purposes at my school, including hooks for classroom to hold instruments. In addition, I earned second place in the Science Olympiad "Flight" event at a regional competition. In my free time, I enjoy drumming and running. This summer, I will be helping to raise money for JOH by teaching science classes.
Louwyn An
I am Louwyn An, a rising 8th grader at John Burroughs. I’ve been learning computer programming and AI/data science for over 3 years. My AI-powered app that automatically identifies different candy types and calculates their nutrient portfolio and my data science project assessing the social acceptability of non-alcoholic beer consumption by adolescents were both published in the peer-reviewed Journal of Emerging Investigators. My systems science project simulating the life cycle and evaluating the cost-benefit of ugly fruit and vegetable consumption received first place and the Bayer Special Award at the St. Louis Science Fair. Join me to learn and ride with AI!
