Miao-Ping Chien joined the Department of Molecular Genetics at Erasmus Medical Center in June 2017. Chien was born and raised in Taiwan, where she studied Molecular Biology at National Yang-Ming University. She obtained her PhD in Chemistry and Biochemistry at the University of California, San Diego, and went to Harvard University for postdoctoral research, focusing on technology development for biology using multidisciplinary approaches.

Why are certain specific, aggressive cancer cells able to resist traditional therapies? Finding the answer to that question drives Miao-Ping Chien’s research: “Resistant cancer cells are extremely elusive. They are able to quickly mutate in unexpected directions, which enables them to withstand chemotherapy or radiation. These cells are rare, difficult to identify, and, therefore, extremely challenging to isolate and analyze. We address this problem in our lab by developing multidisciplinary technologies.”
"Optochemistry" for single cell selection and isolation
Isolation of target cells from a heterogeneous pool is technically difficult when the selection criterion is complex, such as dynamic response over time or morphological features. The majority of technologies for single-cell separation highly rely on static fluorescence or snapshot fluorescent signals, which limits the chance to identify functional and rare single cells. Cancer stem-like or driving cells, as an example, are constantly changing their genetic, transcriptomic and proteomic expression over time, which makes them extremely difficult to isolate via traditional cell separation methods. We address this problem in our lab by improving and developing photoselection tools to isolate desired cells from cultures or tissue based on complex cellular dynamics with a combination of optical and chemical tools.
To accurately monitor aberrant cellular dynamics in real-time, a fast and accurate cell tracking algorithm is critical. We develop image processing algorithms, through which desired cellular dynamics can be analyzed and identified.
State-of-the-art single cell sequencing methods allow profiling whole genomes or transcriptomes of individual cells. However, current methods lack the capability to link aberrant functional cellular characteristics (i.e. aggressive migration) to genomic or transcriptomic profiles; cannot profile sparse subsets of cancer cells (i.e., cancer stem-like cells); and cannot differentiate populations with mildly differing gene expression profiles. We develop functionally annotated single cell sequencing methods to identify variant genes associated with phenotypic traits of interest and to identify genes and pathways that would be otherwise invisible.
DNA-damage Response and Cancer Biology
Understanding the complexity of cancer highly depends on an elucidation of the changes in the underlying regulatory signaling networks. As an example, resistant breast cancer cells have a superior ability to repair DNA damage upon radiotherapy. This ability involves DNA-damage response (DDR) signaling pathways.
We use optogenetics and optical tools that enable temporal and spatial light patterning to investigate genes associated with carcinogenesis. Modulating upstream signals will lead to downstream changes of cancer hallmarks. These experiments, combined with rapid and sensitive read-outs of cell signaling and behavior, can lead to a new understanding of key events underlying cancer in real-time and with high spatial resolution.
Education and career
Miao-Ping Chien studied Molecular Biology at National Yang-Ming University in Taiwan in 2006. During 2006-2008, she was a research assistant in Prof. Ding-Kwo Chang’s Lab in the Institute of Chemistry at Academia Sinica in Taiwan, applying biophysical tools to study HIV and influenza viral infection mechanisms.
PhD in Chemistry and Biochemistry
She obtained her PhD with Prof. Nathan Gianneschi in Chemistry and Biochemistry at the University of California, San Diego (UCSD) in 2013, developing a new method to detect and treat tumors with programmable enzyme-responsive nanomaterials.
Postdoc at Harvard University
Miao-Ping Chien then joined Prof. Adam Cohen’s group for her postdoc research in Chemistry and Chemical Biology and Physics at Harvard University, combining advanced optics and photochemistry to develop methods for live single cell isolation based on functional analysis.
