EE major with strong math/stats background - looking for internship advice

Apologies in advance if I sound like a braggart or come off as annoying. I'm currently a sophomore and I have a 3.1 GPA at a non-target state school. I've taken Calc 1 through 3, ODEs, and linear algebra. I'm currently self-learning PDEs and stochastic modeling. I have a strong background in time-series analysis, as my research in the Department of Electrical Engineering deals with signal processing (clustering of brain-network time-series) and deep learning (training/validation of CNNs for classification of labeled time-series). I get co-authored by a conference this fall if my team's proposed algorithm performs well with further testing. In addition I plan to pursue research in statistical thermodynamics through the Department of Physics, due to my interest in physical random processes and to see if mathematical descriptions of random physical phenomena can be used to analyze financial random processes. I'm very research oriented, and I have a strong interest in finance, however I'm not sure if there are many research positions for undergraduates on Wall Street. I'm not even sure if my resume is good enough to land such a position, if it exists. Wall Street is, as this website suggests, an oasis, and I'm not sure where to start. I'm not looking for a generic quant trading role, if that makes sense. Any input/advice/thoughts would be appreciated.
