我研究不同物种之间如何相互作用以及这如何影响它们的进化轨迹、过去和历史。我的研究主要集中在软体动物,例如蛤蜊、蜗牛、章鱼和鱿鱼等。最近,我的实验室主要关注双壳类动物,例如扇贝、蛤蜊和鸟蛤等。我们研究了巨型蛤蜊与其共生藻类之间的相互作用,以及寄生虫对泥虾的生态和进化影响。作为无脊椎动物馆长,我负责管理博物馆的近百万无脊椎动物标本,并向科学家和公众提供这些标本。我对海洋生态系统的奥秘以及我们对它的未知感到好奇,这总是激励我。在与导师的合作中,我学习到要勇于尝试,即使不自信也要尝试。作为导师,我努力帮助我的学生实现他们的职业目标,并根据他们的需求调整我的指导方式。我从小就对自然和动物充满好奇,这源于我小时候读的威拉德·普莱斯的《探险系列》丛书。在研究生期间,我发现了一种完全没有眼睛的洞穴虾,这让我对进化生物学产生了浓厚的兴趣。野外工作让我有机会亲身接触自然,这总是能带给我灵感。在博士后期间,我学习了共生关系的知识,这促使我进一步研究物种间的相互作用。在巨型蛤蜊的研究中,我们发现它们的一些免疫机制已经丢失,但它们进化出了独特的机制来识别共生藻类。更好地理解巨型蛤蜊与藻类的共生关系对于理解珊瑚礁生态系统和海洋生物多样性的未来至关重要。在野外工作中,最大的挑战之一是缺乏对研究系统的充分了解,以及对目标物种的分布和栖息地的不确定性。即使没有找到目标物种,野外考察也能让我们了解生态系统和栖息地,从而为研究目标物种提供信息。科学研究中,失败并非真正的失败,而是学习不同信息的机会。在泥虾的研究中,我们发现了一种入侵寄生虫,它对泥虾种群造成了严重的影响。我们在美国西海岸对泥虾种群进行了调查,发现了入侵寄生虫的北部边界,这为该物种的监测和保护策略提供了信息。我在西澳大利亚进行的为期六个月的学术休假,是我最难忘的野外工作经历之一。我建议早期职业科学家尽可能多地与他人合作,特别是与那些与你观点不同的人合作,这能激发灵感,创造更具创意的项目。现代科学需要合作,因为任何一个科学家都无法独自掌握所有知识来解答大型科学问题。如果没有任何限制,我最想研究的是共生关系建立的分子机制,特别是幼虫阶段。

Shownotes Transcript

Dr. Jingchun Li is an Associate Professor in the Department of Ecology and Evolutionary Biology at the University of Colorado Boulder, and she is the Curator of Invertebrates at CU Boulder’s Museum of Natural History. She is also a Packard Foundation Fellow and a National Geographic Explorer. Jingchun studies how different species interact with each other and how that has influenced their evolution. Her work focuses mostly on mollusks like clams, scallops, cockles, snails, octopus, and squid. For example, she has recently been examining giant clams that use symbiotic algae to become photosynthetic. As a museum curator, Jingchuin manages the museum’s collection of nearly one million invertebrates. She is responsible for developing the collection, good stewardship, documenting relevant details about each specimen, and making specimens available to scientists and the public. Some of Jingchun’s hobbies include rock climbing at a local gym with her lab members, spending time with her kids, watching musicals, reading, and playing board games like Setters of Catan. Jingchun completed her B.S. in Biological Sciences at Capital Normal University in China and was awarded her PhD in Ecology and Evolutionary Biology from the University of Michigan. Next, Jingchun conducted postdoctoral research at Harvard University with support from an NSF Ocean Sciences Postdoctoral Research Fellowship. Afterwards, she joined the faculty at the University of Colorado Boulder. In our interview, Jingchun shares insights and stories from her life and science.
