I am so glad to come back and become a postdoctoral researcher in the Computer Science and Engineering department at Penn State University, where I work with Prof. Rebecca J. Passonneau and others at the Penn State NLP group, in a list of projects with a focus on applying Artificial Intelligence for Education. Previously I was a visiting student of Becky at Columbia University.
I got my Ph.D. from Tsinghua University in July, 2017. My advisor is Prof. Gerard de Melo who is now moving to Rutgers University. I was a member of the Web Mining and Language Technology group at Tsinghua University, part of the Institute for Interdisciplinary Information Sciences (IIIS), which is led by Turing award winner Andrew Yao. Before that, I received my Bachelor of Computer Science from Beijing University of Posts and Telecommunications, with two publications (indexed by SCI, Impact factor ~3) in the area of quantum information and top ~1% of GPA rank.
Pronunciation of my name is [tʃiæ] (falling tone, the fourth of the four tones in modern Chinese pronunciation) for "Qian (茜)", and [ja:ŋ] (rising tone, the second one) for "Yang (杨)". It's my honor to have an English name "Lara" from Prof. William S.-Y. Wang, a famous linguist.
My research focuses on a wide range of topics in Natural Language Processing (especially Text Summarization, Open Information Extraction, Knowledge Graph, Machine Translation), Deep Learning, and the intersection of AI and HCI. For example,
Text Summarization: We propose PEAK, the very first method for automatically evaluating the quality of a summary using the Pyramid method. PEAK shows great promise for automated scoring and assessment of manual or automated summaries, opening up the possibility of widespread use in the education domain and in information management.
Machine Translation: To overcome the data scarcity problem for resource-scarce language pairs, we introduce a joint training algorithm for pivot-based neural machine translation, which leads to significant improvements over independent training across various languages.
Deep Learning: We decouple the backpropagation by breaking the backward lock using delayed gradients, which accelerates the training of deep learning models significantly without loss of accuracy.
Human-Computer Interaction: The staggering amounts of content readily available to us via digital channels can often appear overwhelming. So we create HiText, a simple yet effective way of dynamically marking parts of a document in accordance with their salience. HiText relies on a deep learning-based sentence ranking method that results in marked increases in user satisfaction and reading efficiency.
We provides a Java implementation of PEAK, the first tool to automatically generate the pyramid models that enables the whole automatical assessment of both human and machine summaries.

You would never know the host is now very hungry.
Assistant for Graduate Students of IIIS, 2013
When organizing this autumn outing, some students wanted to go hiking but some only wanted to go to the KTV or play games, and the other preferred to eat delicious food just as me. Finally I found a place where we made all the ideas come true.
We organized a successful Doctoral Consortium with PhDs from both Computer Science and Physics.
This is a chorus competition host by Tsinghua University, but the judgers come from the top singers in China. As the assistant, I'm proud of the prize we won!
I love basketball very much and I can throw at least 4 balls given 5 ones into the basket. BTW, could you find me in the second pictures? (Hint: just find a girl out of all the other men players in the football team.) It's the first time the team won a competition!
