Electrocardiogram-Based Abnormal Heartbeat Classification: A Deep Learning Approach for Arrhythmia Detection

By: Aditya Kendre Heart arrhythmias are irregular rhythms in heartbeats that affect 3 million people worldwide every year. Due to the increasing rate of ECGs recording for diagnosis, it is now possible to devolve autonomous AI driven systems to identify arrhythmias in ECGs. A convolutional neural network (CNN) was developed and trained, to achieve accuracy on par or better than …

Graphene Oxide-Based Hole Transport Layers for Organic Solar Cells

By: Yash Sahoo My project involved working with organic solar cells (use organometals instead of purified silicon; function similarly) to reduce the cost of manufacturing cells while keeping similar energy efficiency. Specifically, my project involved working with special thermoelectric polymers which were used as semiconductors with the addition of graphene-based dopants to improve specifically a single layer (hole transport layer). …

Which Factors Increase the Risk of Contracting the Common Cold?

By: Elizabeth Lesher This project was an epidemiological study that seeks to identify both risk and protective factors for the common cold (i.e., characteristics that make a person more or less susceptible to contracting the common cold). To carry out this project, I collected demographic, lifestyle, and genetic information from over 200 participants and used a range of statistical tools …

Biofilm Structure and Formation in Haemophilus ducreyi

By: Delaney Lacey Biofilms are of particular interest to the scientific and clinical community due to the variety of biotic and abiotic surfaces they can colonize. Teeth, surgical instruments, and organs (such as the lungs of cystic fibrosis patients) can all be colonized by a bacterial biofilm. Biofilm formation is characterized by the following steps: signaling by an environmental cue, …

Combating Malnutrition: The Effect of Eggs on the Development, Learning, and Memory of Drosophila melanogaster

By: Gwyneth MacDonough My project aimed to determine if malnutrition’s effects on development and cognition in Drosophila melanogaster could be reduced by consumption of eggs. I also attempted to find the optimal period for dietary intervention. To conduct my experiment, I reared seven groups of Drosophila on specific combinations of three different diets – malnourished, egg-enriched, and control. I then …

Real-time Imaging of α-Synuclein-Induced Damage to Neuronal Membranes in Parkinson’s Disease

By: Jacob Parres-Gold For the last three years at Cal State LA, I have worked in the lab of Dr. Yixian Wang. Our project aims to study the role of the protein alpha-synuclein in the death of neurons associated with Parkinson’s disease. We study how alpha-synuclein aggregates and how these aggregates interact with and damage the cell membrane. We have …
