Dr. Yun Wah Lam received his PhD training in the lab of Dr. Davina Opstelten at the University of Hong Kong. After receiving his PhD in 1997, he joined the group of Prof. Angus Lamond in Dundee, Scotland, where he developed an interest in the relationship of the architecture of mammalian cell nucleus and the regulation of gene expression. Lam uses live-cell imaging techniques and classical biochemical approaches to study protein localization and interactions in the cell nucleus. In parallel, he is involved in an international effort to map the human nucleolus proteome. Recently, in collaboration with Jens Andersen (Odense) and Matthias Mann (Munich), he adopted the technique of SILAC (Stable Isotope Labeling with Amino acids in Cell culture) to quantify, by mass spectrometry, the global dynamics of the human nucleolar proteome in response to changes in metabolic conditions. The resulting paper, having received over 100 citations in 24 months, was featured as the "ScienceWatch hot paper" in The Scientist magazine (March 2007). Lam was the recipient of the second prize of the Roche "Imagining the future" contest in 2006. He joined City University of Hong Kong in 2007.
Research Interests and
Proteomics allow the large-scale identification
of proteins in complex biological systems, but it
often only produces static snapshots of proteomes
that fail to describe and explain the dynamic nature
of cellular behaviours. In contrast, modern cell
imaging techniques allow the quantitative analysis
of the spatial and temporal distribution of
biomolecules in living cells, but only a relatively
small number of proteins can be studied in one
experiment. Our lab strives to bring together these
two powerful methodologies to tackle fundamental
biological questions. To this end, we perform
quantitative mass spectrometry to measure the flux
of a large number of proteins through subcellular
spaces and to track the proteomic changes within
cellular complexes through time. In parallel, we
record these dynamic cellular behaviours in live
cells using time-lapse fluorescence microscopy. From
these two angles, we aim at building coherent
pictures of intracellular events under different
growth and metabolic conditions. This lab aims to
apply this dual approach to a range of topics, from
basic cell biology to environmental sciences.
