New York University, Tandon school of Engineering Brooklyn, NY Master of Science in Electrical Engineering, GPA: 3.71/4.0 09/2016 - 06/2018 University of Science and Technology of China, School of Information Science and Technology Anhui, Hefei Bachelor of Engineering in Automation 09/2012 - 07/2016 PROFESSIONAL EXPERIENCE

Abphina LLC 06/2019 – 12/2019

Data Scientist

• Processed, cleaned, and verified the integrity of data used for malaria case analysis. (Excel/Python)

• Built models with multiple methods (Linear Regression/SVM/Decision Tree/Random Forest) to analyze the effect of climate features on malaria and achieve over 85% precision and recall rate on outbreak prediction.

(Pandas/Sklearn/Tensorflow)

• Reported directly to the team leader and communicate with other research teams with presentation and research paper. Broad USA INC 11/2018 – 02/2019

Energy Efficiency Engineer (Machine Learning)

• Developed an application on multiple operation system (Mac OS/Windows/Linux) with ML algorithm to help customers choose proper products, reduce the time cost of sales by 20%.

• Built automated data pipeline (SQL, Spark, Restful API) for multiple departments. Analyzed sales operation and components data and built UI dashboard with Tableau & python to visualize & deliver data insight.

• Built a dynamic machine learning method that helps analyze the energy usage record and enhance the energy efficiency of building by 5%. The final cost saving achieved 30,000$ per year.

• Published a data supported article on a magazine in absorption chiller industry. Elbum LLC, New York, NY 08/2018 – 11/2018

Machine Learning Engineer

• Designed model to perform wandering detection for security business (ATM).

• Utilized deep learning model to recognize and track wandering people from real-time camera signal (Python, Tensorflow/OpenCV, GPU)

• Added data pipeline to preproduce the real-time video signal by fps reduction and color equalization. (Hadoop, AWS, SQL)

• Merged the model to a smart building system and passed the pressure test PROJECTS

Self-driving Assistance System for Autonomous Car 01/ 2018 –05/2018

• Designed a program in Python by combining built-in functions with OpenCV(cv2), RCNN and Mask-RCNN.

• Detected lanes, cars, signs and surroundings from video signal for self-driving vehicles.

• Further gave command basing on orientation and distance offset generated from highly accurate detection. L-BFGS Based Adversarial Input Attacks Against DNN (Python, GPU) 01/2017 – 05/2017

• Designed a model to generate adversarial image to attack(mislead) a pre-trained DNN network.

• The success rate is over 85% for all target numbers and 95% for specific target numbers.

• Achieved the potential to improve the accuracy and robustness (e.g. prevent from misleading images attack) of DNN. MNIST Handwriting Image Recognition(R) 01/ 2017 – 05/2017

• Designed a project to recognize handwriting numbers with diverse methods in R.

• Wrote custom SVM, K-Means, CNN functions and made comparisons (e.g. accuracy, efficiency, recall rate, etc.).

• Achieved 92% accuracy rate and further enhanced the processing time by 30%. OTHER PROJECTS

• Controlling Algorithm Design for Automatic Vehicle (ROS, Python) 10/2017 – 05/2018
