Menglong Zhu
Menglong Zhu is a computer vision engineer and a coauthor of MobileNets, the compact neural networks Google released in 2017 for on-device and embedded vision. Trained at Fudan University and the University of Pennsylvania, they completed a PhD at Penn's GRASP Lab under Kostas Daniilidis in 2016. At Google, Zhu was a core team member of the entry that won the 2016 COCO detection challenge, contributed to the TensorFlow Object Detection API, and coauthored MobileNetV2 and an integer-only quantization scheme for mobile inference. They now work at DJI, where they coauthored a 2022 binary neural network framework for on-device computer vision.
Timeline
-
2010–2012
Fudan and a Penn master's
Zhu earns a bachelor's degree in computer science at Fudan University in 2010. In 2012, they complete a master's degree in robotics at the University of Pennsylvania.
-
2013–2014
Actemes and deformable part models
In 2013, they coauthor the ICCV paper "From Actemes to Action" with Weiyu Zhang and Konstantinos G. Derpanis, introducing a video dataset that labels the action and body keypoints in every frame. At ECCV in 2014, they publish Active Deformable Part Models Inference, a fast object detector, with Nikolay Atanasov, George J. Pappas and Kostas Daniilidis.
-
2016
A GRASP Lab PhD
In 2016, they complete a PhD in computer information science at Penn's GRASP Lab, advised by Kostas Daniilidis, and then join Google. With Jonathan Huang, Kevin Murphy and other researchers, they coauthor a November 2016 guide to speed and accuracy trade-offs in Faster R-CNN, R-FCN and SSD object detectors.
-
2016–2017
COCO win and the detection API
Zhu is a core team member of Google's G-RMI entry, which places first in the 2016 COCO detection challenge. In June 2017, Google releases that detection system as the TensorFlow Object Detection API, an open-source framework for building, training and deploying detection models, with Zhu as one of its core contributors.
-
2017
MobileNets for on-device vision
In April 2017, they coauthor MobileNets with Andrew G. Howard, Bo Chen, Dmitry Kalenichenko and others; the models use depthwise separable convolutions and two global hyperparameters that trade off latency and accuracy. Google releases MobileNets for TensorFlow in June 2017, announced in a blog post by Howard and Zhu.
-
December 2017–January 2018
Integer inference and MobileNetV2
In December 2017, Zhu coauthors a quantization scheme that runs neural network inference with integer-only arithmetic, together with a training procedure that preserves accuracy after quantization. MobileNetV2, written with Mark Sandler, Andrew Howard, Andrey Zhmoginov and Liang-Chieh Chen, appears in January 2018; it is built on inverted residual blocks with thin bottleneck layers and adds the SSDLite detection framework.
-
March 2019
Memory-guided mobile video detection
In March 2019, they coauthor "Looking Fast and Slow" with Mason Liu, Marie White, Yinxiao Li and Dmitry Kalenichenko. The video object detector pairs lightweight feature extractors with a temporal memory and runs at speeds of up to 70+ FPS on a Pixel 3 phone.
-
As of October 2026
Binary networks at DJI
In February 2022, with colleagues at DJI Innovations, Zhu coauthors a binary neural network framework that overtakes 8-bit quantization in the speed-vs-accuracy tradeoff for classification, detection, segmentation, super-resolution and matching. They work at DJI.
