I graduated in July 2016.
My entire curriculum was taken in Mandarin, incl. engineering coursework as well as courses in multi-cultural communication and science and technology in China. My research dealt with the use of advanced materials, namely fiber composite materials and recycled concrete aggregates, in civil engineering applications. I also gained significant experience in the use of finite element modeling software for element and structure-level modeling. While there, I co-authored three published research papers and my master’s thesis.

Activities and Societies: Men's Crew, Chinese Language Tutor, Eagle Scout
I received my undergraduate degree at the University of Notre Dame, where I received dual degrees in Mandarin Chinese (BA) and Civil Engineering (BS).
My college curriculum included common engineering softwares such as finite element softwares, MATLAB, and AutoCAD, research experience (including concrete and green energy), language study, and a year spent abroad at Peking University in Beijing in an intensive language program. -

Scatter in the Mechanical Properties of Recycled Concrete Aggregate Columns Confined by Hand-Laid GFRP under Axial Compression
Conference on Fiber-Reinforced Polymer Composites in Civil Engineering
Presents a comparative study of the axial load-bearing capacity and stress-strain curves of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC) columns confined by hand laid-up glass fiber reinforced polymer (GFRP). One significant problem in using RAC in a structural role is the unpredictability of its load-bearing capacity, thus this paper presents a large amount of experimental data to analyze the scatter of confined and unconfined concrete columns. Results indicate that…
Presents a comparative study of the axial load-bearing capacity and stress-strain curves of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC) columns confined by hand laid-up glass fiber reinforced polymer (GFRP). One significant problem in using RAC in a structural role is the unpredictability of its load-bearing capacity, thus this paper presents a large amount of experimental data to analyze the scatter of confined and unconfined concrete columns. Results indicate that GFRP confinement reduces the scatter in the stress-strain response of RAC columns (i.e. stresses across multiple members are more uniform at a given strain), but owing to the unpredictability of the ultimate rupture state of hand laid-up GFRP, it is ineffective at reducing the scatter in ultimate load-bearing capacity. Regardless of variability in ultimate stress, GFRP confinement also limits variability in axial strain at failure compared to unconfined RAC columns. Additionally, systematic differences in radial stress-strain response between NAC and RAC GFRP-confined columns were demonstrated by the test program and are discussed in this paper.

Mechanical Behavior and Design of FRP Structural Members at High and Low Service Temperatures
Journal of Composites for Construction
Current design manuals for fiber-reinforced polymer (FRP) structures only allow limited application of FRP in high-temperature environments. However, the residual mechanical properties of FRP composites at high service temperatures should be considered. This paper presents the results of bending tests on FRP coupon specimens at temperatures from 25 to 120°C and of compression tests on FRP components at temperatures from −40−40 to 90°C. Although the mechanical properties decrease with increasing…
Current design manuals for fiber-reinforced polymer (FRP) structures only allow limited application of FRP in high-temperature environments. However, the residual mechanical properties of FRP composites at high service temperatures should be considered. This paper presents the results of bending tests on FRP coupon specimens at temperatures from 25 to 120°C and of compression tests on FRP components at temperatures from −40−40 to 90°C. Although the mechanical properties decrease with increasing temperature, they retain residual strength and stiffness at high service temperatures. The influence of subzero temperatures on the mechanical properties is negligible. Additionally, the flexural properties of the coupon specimens and the compressive properties of the components were experimentally investigated after high-normal temperature cycles, which alternated between 45 and 135°C every 12 h. The results show that repeated high-normal temperature cycles have little effect on the mechanical properties. The simultaneous effects of loading and high-temperature environments on FRP structures should be considered during design. Thus, this paper proposes a design method for calculating the loading capacity of FRP members at different temperatures. Experimental data from literature and this study were normalized and compared with the results predicted by this method. As expected, the proposed method provides a lower envelope of experimental data for both strength and modulus. Thus, the design method can conservatively estimate various mechanical properties of FRP structural members under different loading conditions at high service temperatures. Additionally, the method can be conveniently established and applied in design.
